I changed the world

He first carefully took four pictures of the ancient coin under the light, then casually registered an online name called "sfdfgh" on the website, and then opened a post in its "Appraisal Area" section: By the way Huatongbao gold coin, please help me identify it.

In addition to the four photos, he also wrote a paragraph: It was handed down from ancestors and is gold. I personally don’t know much about Guquan. I would like to ask you guys, how much is it worth?

After posting this post, there was no result for a while. Zhang Jing put the gold coins in the drawer. He felt uneasy after thinking about it. He moved them to several places to store them, but he still felt uneasy. Finally, he sighed and put them away. He stuffed it into his wallet, which he decided to keep close to his body for the next few days.

Summoning the wish book again and looking through it, Zhang Jing found that it had not changed much. The latest page still only had the extra words from the morning:

Wish: I want to get a 100 million yuan empire coupon without breaking the law.

It seems that simply getting gold coins is not enough. Maybe you have to wait until you get money to fulfill your wish.Zhang Jing thought to himself.

Seeing that it was still early, Zhang Jing stood up, changed into a set of sports autumn clothes, stuffed his wallet in the inner pocket of his clothes, took the damaged clothes and pants and went out.

If it were true in his previous life, he would definitely throw away such damaged clothes, but now, he is reluctant to do so. After all, in this world, it is common for ordinary people to repair and repair damaged clothes, but it is really beyond repair. , would rather keep it as fabric than throw it away.

However, with Zhang Jing's skills, it was really difficult for him to repair a hole of this size. Even if it was repaired, it would be ugly. Therefore, he decided to go to a tailor shop not far away.

The tailor shop Zhang Jing was looking for was not far away, just a few dozen meters away. The shop was located in a family's home. It was a common two-story wooden house here, separated by rough wooden boards. The height of both the ground floor and the attic is only about 2 meters.The proprietress's family of five lived in the house. The ground floor was used for business and the attic was occupied by people.

Zhang Jing walked in. In the dimly lit room, a woman was sitting in front of a sewing machine, working. She turned her head when she heard the noise, then stood up and bowed slightly, her old face full of expressions. Some smiles came: "It's Brother Jing, do you have anything to make up for?"

"Sister-in-law Yu, it was unlucky for me to go out today and I fell down. No, my clothes and pants were all torn. I want you to mend them." Zhang Jinglue said after holding up his hands. The husband of this sister-in-law Yu was named Yu, and her real name was Wang. Because she took her husband's surname after getting married, everyone called her Yu Sao or Yu Wang.

The proprietress named Mrs. Yu is a long-time resident here. This tailor shop is the craft she relies on to make a living. The price is cheap and the craftsmanship is exquisite. Therefore, the surrounding residents will come to her whenever they need to repair and upgrade their clothes.

"Don't worry, I'll mend everything for you." After opening the clothes and making some gestures, Mrs. Yu nodded. She opened her mouth to say something, but suddenly she covered her mouth with her hand and coughed suppressedly.

"Sister Yu, are you okay? I think you don't look good." Zhang Jing said worriedly.

"It's okay, it's okay... Just drink some water and you'll be fine." She stroked her chest and calmed her breath, and Sister-in-law Yu felt better: "It's all an old problem. I have some asthma and it will attack when the season changes. It's not a problem. "

"Put these here with me first. You can just come and pick them up in the evening."

"Then I'll take my leave. Sister Yu, you'd better go to the hospital when you have time. Your health is important." Zhang Jing cupped his hands.

After leaving the tailor shop, Zhang Jing deliberately took a detour to the Jiqingfang bus stop to inquire about the news. When he arrived at the bus stop, he found that it was crowded with passers-by. He squeezed into the crowd and found that the front had been surrounded by a temporary fence. , there are police patrolling back and forth behind the fence.

The huge pit was still open. From Zhang Jing's perspective, he could see some people at the bottom of the pit holding some tools and carefully exploring something.To him, it didn't look like they were building a road.

There was a middle-aged woman on the side pointing in the direction of the big pit and talking about something to others. Zhang Jing then leaned over and asked in a low voice: "What is going on?"

The woman turned her head to look at him, and then said: "This bus stop was crushed by an incoming bus not long ago. Later, the road administration came to check and it seemed that some ancient tomb was discovered."

As she said that, she pointed at the people exploring the pit: "Look, it should be the archaeological team that came over for rescue excavation. I heard that they are people from Southeast University who have just arrived."

Due to traditional reasons, digging graves is a taboo in the current Dazhao period and will be criticized by public opinion.Therefore, under normal circumstances, even professionals will not touch those intact ancient tombs, even if they are ownerless, under normal circumstances. This is usually only done when the tombs are damaged or due to some accidents. Rescue excavation will only be carried out when the tomb is exposed.And that should be the case now.And if the descendants of the tomb owner are still alive, they can make a claim on the funerary objects in the tomb.

Nuonuo said a few words, and Zhang Jing withdrew from the crowd. He had already roughly understood the situation. It seemed that he had accidentally encountered an ancient tomb, and the Hue Tongbao money he got should belong to the ancient tomb. One of the funerary objects in the tomb.

I don’t know why this ancient tomb was not discovered when the road was being built... Zhang Jing thought to himself, and was even more shocked by the almost weird ability of the wish book.

Chapter 5 A million-dollar deal!

In the evening, Zhang Jing went to the tailor shop to retrieve his clothes. The damage had been completely repaired, and he had even washed, dried and ironed them.As long as you don't look closely at the previously damaged areas, you won't be able to see the traces of damage. This cost Zhang Jing 30 yuan in craftsmanship fees.

After a simple dinner, Zhang Jing opened the "Dazhao Ancient Spring Network" again and clicked on the previous post. He was surprised to find that his post had a tendency to become a hot topic on the forum. There were already 6 pages of comments under it. many.

Excluding the "sofas" in front, "watching the wealthy people", "gold coins! Rare, just wait for the boss to come to class..." and other meaningless posts, Zhang Jing saw on the second page, there was a forum with a high level. The ID replied:

"Good thing. Look at the door. Hue Tong Bao money is really rare and should be genuine."

On the third page, another high-level ID replied:

"The Hue Emperor of the Qian Dynasty only reigned for 8 years, which was relatively short, so the price of ordinary Hue Tongbao has always been higher in the market. This is a gold coin. If I remember correctly, it should be when the Hue Emperor ascended the throne. It was cast as a gift to ministers. At that time, the Ministry of Rites cast gold and silver coins. Gold coins were especially rare in the world. According to historical records, the mold was destroyed after the casting was completed. The original patina of the poster is simple. When you look at the door, it is such a treasure!"

These two replies were surrounded by a large number of melon-eating posts, including many asking for prices, and some even asking for Zhang Jing’s address to confirm and negotiate the price. Zhang Jing ignored these posts for the time being and continued to look at them. .On the fifth page, there was a reply from a forum moderator with the forum ID "Ji Quan Zhai Zhu" that made him very excited:

"Hue Tong Bao, a piece of money with Chinese characters on the back, is rare. There are currently less than ten handed down in the country, and most of them are in museum collections. One of them appeared in the autumn auction of Fu Bidu the year before last, and it was finally sold for 85. Looking at the picture, the quality of the original one is even slightly better than that one. The patina is natural, it’s a good thing!”

After that, there were no more valuable posts. Most of them were posts such as "Caught a diving master", "Mr. Yunshan has made up his mind, it seems to be genuine.", "Learned". Kind of nonsense.

In addition, Zhang Jing also found that there were 4 more emails in his website mailbox. When he opened it, three of them were asking for prices, and the last one happened to be the email from the "Master of Jiquan Zhai". The content was relatively simple. It started with a polite exchange of greetings, and then asked him if he was willing to sell the gold coin. He was willing to pay the price of 100 million yuan for the imperial roll, and then left his phone number.

Zhang Jing thought to himself, it should be here!

However, to be cautious, Zhang Jing still searched the forum for the previous posts and information of this "Ji Quan Zhai Master".Later, it was discovered that this man not only had a lot of fans on the forum, but was also a well-known collector in the ancient spring collection circle and a director of the ancient spring collection association in a certain province. Looking at the photo, he looked like an old man with a scholarly bearing, and looking at his past posts , basically answers all questions without being fussy, so it has a good reputation.

What makes Zhang Jing most satisfied is that from the posts about this old man, it can be found that this old man has also purchased ancient coins from many people on the forum, all of which are rare varieties. From the results, these The transaction should have been completed quite smoothly.Nothing bad was said from either side.

In his previous life, Zhang Jing would not have considered safety factors too much due to his confidence in good public security, but this was not the case in this life. He felt that he still needed to be careful.Now this verification made him feel very satisfied. After thinking about it for a while, Zhang Jing picked up the phone and dialed the number.

After a busy tone, the phone was connected, and a rather elegant-sounding old man's voice came from the other side. Zhang Jing briefly introduced himself, and the other person's tone suddenly became enthusiastic.

The old man claimed that his surname was Yang Minghao, his courtesy name was Yunshan, and he was from Beijing.It can be seen that he is also quite sincere and his words are very polite.After the two parties chatted for a while, the topic turned to the Hue Tongbao. The old man did not deliberately find fault with it in order to lower the price like some buyers did, but made no secret of his love for this ancient coin.

At the same time, in terms of price, he added a premium of 15 to the price at the Forbes auction the year before, giving a price of 100 million, which is also a relatively generous price.

According to the old man, if Zhang Jing chooses to go to the auction house to bid on his own, excluding handling fees and storage fees, Zhang Jing can only get about 85% of the auction proceeds. Even if the increase in the market price is taken into account, at most it will be this price.

Because of his previous life experience, Zhang Jing was not unfamiliar with the collection auction process, and he knew in his heart that the old man had not deceived him.Therefore, he no longer hesitated and expressed that he did have the idea of ​​​​taking action. If Mr. Yunshan was interested, he was willing to make this deal.

Both parties were very happy and quickly agreed on the details. Since the two parties were not in the same city, they agreed that the old man would first confirm the flight itinerary and fly directly over. After confirming the specific time of the ticket, the two parties would make an appointment to meet at a location.Finally, the two parties also exchanged their respective "Qianluo" accounts. "Qianluo" is Dazhao's most popular mobile chat tool, similar to WeChat in his previous life.

From beginning to end, both parties had a tacit understanding and did not mention any topic about the origin of the collection.

Early the next morning, Zhang Jing, who had just finished checking in at work, received a message from the old man on Qianluo. The old man told him that he had booked a ticket for noon the next day and would arrive at Linzhou International Airport around 15:[-]. Linzhou is the city where Zhang Jing is currently located. It has been an important water transportation town since ancient times, a large port in the southeast, and a land of plenty.

Therefore, the two made an appointment to meet at a four-star hotel called "Jiang'an Star" next to the airport tomorrow afternoon. Zhang Jinghui had booked a room in advance and waited there.After the deal is concluded, the old man will fly back directly on the plane that night.

........................

Around 22:[-] that night, Zhang Jing finished washing and before falling asleep, he lay on the bed and checked his mobile phone. A local message in the News APP attracted his attention. He clicked on it and took a look:

Yesterday, the cause of the subsidence at the Jiqingfang Station bus station in our city has been identified. The road management company discovered an ancient tomb from the Qian Dynasty underground where the original bus station collapsed. Currently, a team led by Professor Li Zichen from the Department of History of Southeast University has begun rescue excavations. , it was initially determined that the owner of the tomb was suspected to be the tomb of Wang Dingbang, an important minister of the Qian Dynasty.Wang Dingbang once served as the admiral of Jiangnan in the third year of the reign of Emperor Qian Dynasty, and later became the prince Shaobao. The Wang family was once a prominent family in Jiangnan. Later, because he was trapped in the isolated city and refused to surrender when the rebel army swept across Jiangnan at the end of Qian Dynasty, he was massacred by the Zuo Baoxing tribe of the rebel army at that time.Historically, there have been many speculations about Wang Dingbang’s cemetery...

Chapter 6 Interns

"Sister Lingzi, I'm going to take half a day off in the afternoon. I have some urgent personal matters to take care of." On the morning of the second day, not long after he started working, Zhang Jing walked to a woman's workstation not far from his own. vocal channel.

"Do you have to do it today? The new game has not been online recently, and the team has a lot of work." This is a woman with light makeup, with thin cheeks and thin lips. She is about 30 years old. She raised her head and wrinkled after hearing this. He frowned.She thought for a while and then said: "You just asked for a day off yesterday. Why don't you ask for it again next week? Let's get over this period."

"No, the matter is urgent. Please leave it to Sister Lingzi..." Zhang Jing shook his head and said firmly.

"What is it probably?"

"It's a more personal matter, it's not convenient to talk about it..."

After staring at Zhang Jing for a few seconds, she pinched her brows and said: "Okay... you go and be an OA. You must pay close attention to the work at hand. If it affects teamwork, it will affect your ability to become a full-time employee in the future."

Zhang Jing pretended not to hear the displeasure in the other party's tone, thanked him, turned around and walked back to his work station.

"What's the matter? It seems that Sister Lingzi is not very happy?" Sun Yunxing, a fellow intern who entered the company at the same time at the work station next to him, came over to ask. This guy usually likes gossip about his employer's head, the Li family. Jing doesn't like him very much.

"Nothing, I asked for leave this afternoon." Zhang Jing smiled and shook his head, and said no more.

Seeing that Zhang Jing didn't say much, Sun Yunxing felt a little bored. He mumbled something softly and turned away to look away.

In fact, he was considered a veteran in the workplace in his previous life, and he completely accepted the idea of ​​becoming a full-time employee.As early as the first day he traveled through time, he saw the company's hiring practices. Because the salary level of interns was much lower than that of regular employees, the company recruited a large number of interns for a long time and set the internship period to half a year. , based on his observation, very few people can eventually become regular employees. The so-called regular employees are nothing more than a pie drawn out of thin air by the company for these unsophisticated newcomers.

..............................

Linzhou Airport is located in the northern suburbs of Linzhou City. Linzhou is the capital of Jiangdong Province and one of the largest cities in the southeast of the empire. Therefore, Linzhou Airport has been built as a regional hub airport since its establishment.

Zhang Jing took the subway to the airport. Linzhou City's public transportation adopts a subway-based and bus-assisted mode. The subway lines completed ten years ago can cover the main urban areas of the city.

The architectural style of the airport is very modern, with an all-metal structure and glass veneer. Looking down from a high altitude, it looks like a huge black lotus blooming on the ground. On the west side of the airport is a large area that is closed for construction. From the official announcement According to the news, what is under construction here is the Linzhou City aerospace aircraft homeport. In the future, you can directly board an aerospace aircraft from here to fly to the Hope City of the moon. It is the first human being to transcend the national scope and belong to the Human League (referred to as the Human League) free city.

Since various countries signed and promulgated the "Free Moon Act" in 1988 at the Gomen Castle in the capital of the Seljuk Empire, the City of Hope has become the headquarters of the Human Joint Defense Command (HUDC) and the largest aerospace industry center in mankind. Due to its unique location Due to its low gravity advantage, most of mankind's current heavy airships are almost offline from here.Due to the massive influx of investment, Hope City's resources and talent pool can be said to be in a state of expansion at all times.

Zhang Jing walked out of the subway station from the exit of the large square in front of the west gate of the airport. The square was crowded with people. The four characters "Linzhou Airport" were hung in official script on the building on one side. The Earth Defense Force was playing on the big screen next to it. The recruitment advertisement for the First Fleet showed a scene of an assault by orbital airborne troops. Several "Hill-class" landing ships were breaking into the planet's atmosphere. It was so majestic that many passers-by stopped to watch.

The First Fleet of the Earth Defense Force is affiliated to the Human United Defense Command (HUDC). Its imaginary enemy is to defend against invasion from outer space. Its home port is located in the Beacon Castle in the debris belt of the ancient Cypress planet on the edge of the solar system.

After traveling through time, what amazed Zhang Jing the most was that the aerospace industry in this world was indeed more than one era more advanced than in the previous life, and this was also related to the major event that changed the history of the world 100 years ago... …

He took out his mobile phone and checked the time. It was now 14:30 in the afternoon. The "Jiang'an Star Hotel" where Zhang Jing had made an appointment to meet was less than 100 meters away. Zhang Jing looked around and saw it. The hotel sign not far away.

Entering the hotel lobby and booking an hourly room on the second floor, Zhang Jing edited a message and informed the old man of the room number. Then he sat on the sofa in the room and started waiting while scrolling through his phone.

About half an hour later, just as Zhang Jing was getting impatient and was about to stand up and move around, there was a knock on the door.

Zhang Jing hurriedly walked forward and opened the door. Standing outside the door was a fat, smiling and elegant old man. He was wearing a light gray narrow-sleeved Confucian dress and a square crown on his head. This kind of clothing is actually a variant of Confucian clothing that has been improved by modern aesthetics. Compared with traditional clothing with wide robes and long sleeves, this type of clothing is more convenient for traveling and is quite popular among contemporary nobles and scholars.

Zhang Jing hurriedly handed over his hands, and the old man returned the favor. The two said hello to each other, and then he let the old man into the house.

In this world, because the inheritance of Eastern culture has continued consistently, the traditional etiquette is not as simple as it was in Zhang Jing's previous life.

The room is not big. There are two single sofas by the window, and a small coffee table in the middle of the sofa.

The old man seemed to be more talkative. After the two introduced each other, they sat on the two single sofas in the room. First, they chatted for a while about what they had seen on the plane. After setting the atmosphere, Zhang Jing took a seat from the inner pocket of his clothes. Zhong took out the coins wrapped in paper towels, opened the paper towels, and carefully placed the coins on the coffee table in the middle of the sofa.

The old man did not go to get it immediately, but waited until Zhang Jing stabilized the coin and withdrew his hand.Then he unhurriedly took out a glasses case from his pocket, took out a pair of tortoiseshell-rimmed glasses, and put them on his face.

Then, he took out a pair of thin cotton gloves and put them on, then reached for the coins and looked at the light from the window.

After a while, he took a long breath and sighed: "It's really good, it's so well preserved."

In fact, with the old man's eyesight, it can still be seen that no matter from the coating or the degree of cleaning, this is more like a newly unearthed coin. Therefore, Zhang Jing's so-called ancestral theory does not actually matter. Too trusting.However, in the antique business, the origins of the collections are diverse, and some of them have an unexplained relationship with tomb robbing. Therefore, it is not necessary to be too realistic about the origins of the objects. Sometimes it will change the atmosphere. It was stiff, so the old man did not intend to reveal this point.

Chapter 7 Received 100 million!

"How do you plan to trade, little friend Hongjian? Can you use a bank card to transfer money?" The old man did not delay and went straight to the topic.

"Of course, just transfer it to this card." Zhang Jing took out a bank card from Southern Bank from his wallet. This is Zhang Jing's only bank card. There is still 1530 yuan in the card. Southern Bank is a bank card. There are several large commercial banks, especially in the southern provinces of Jozhao. It is said that there are shares of the famous Jiangdong Consortium behind them.

The old man took out his mobile phone and once again confirmed with Zhang Jing that the transaction amount was 100 million yuan. After both parties confirmed that it was correct, he used the transfer function of online banking to transfer 100 million yuan to Zhang Jing.

While waiting for the money to arrive, the two chatted for a while about the evolution of ancient coin shapes. In Zhang Jing's view, the old man was indeed very knowledgeable in this area. Although it was just a casual chat to kill time, it also made him listen. He enjoyed it very much and asked some questions from time to time, which the old man also answered.

About 5 minutes later, a notification sound came from Zhang Jing's mobile phone. When he opened it, he saw a text message from the bank, indicating that 100 million in cash had arrived in his account.He hurriedly opened the online banking to confirm. When he saw that the current amount of the account was displayed as 1001530 yuan, he felt sure.

"The account has been received, then I have no problem here." Zhang Jing put down his phone and smiled at the old man.

"That's good, then we'll settle this deal." The old man smiled when he heard this.

"Of course it's settled." Zhang Jing also understood the implication of the old man's words. The collection circle pays attention to the settlement of money and goods, and risks depend on one's own eyesight. If the price of the goods is increased in the future, it is impossible to regret it.

"Then if Mr. Yunshan has nothing else to do, I will take my leave." Zhang Jing said with a smile.

"Then I won't keep you, little friend, go away."

"Mr. Yunshan has the air of an elder, and I have benefited a lot today." Zhang Jing stood up and handed over his hands: "I will listen to your teachings again if I have the opportunity in the future."

The two of them exchanged polite greetings again, and the old man sent Zhang Jing to the door and watched Zhang Jing go downstairs.

Going downstairs to the front desk, Zhang Jing paid for the old man's room for 5 hours in advance. During the chat just now, he already understood that the old man had already booked a return ticket when he arrived, which was around seven o'clock in the evening.

The mood was quite exciting along the way. Although Zhang Jing's net worth exceeded this figure in his previous life, that also included the value of real estate such as real estate.What's more, this money still has considerable purchasing power in this world. As long as Zhang Jing doesn't buy a house immediately, the normal expenses will be enough for him. After all, for many middle- and low-income families, this has been their entire life. No money can be earned.

Changing from the subway to the bus, suppressing his excitement all the way, Zhang Jing returned to the slums in Jiqingfang, carrying the vegetables he picked up on the road, ready to go home and cook dinner.It was already 17:20 in the afternoon. Walking in the alleys of the slums, you could see unemployed men squatting on the ground in twos and threes basking in the sun everywhere, and puppies chasing each other among the garbage.A woman was washing her hair at the door. Several promotional posters of idol groups that had changed their color were posted on the wall. Girls in school uniforms and bows were leaving school together. Some children gathered in the open space to play football...

He even saw a porridge shed, which was used by some homeless people as a temporary resting place. Some gentry from Linzhou would give porridge here from time to time, usually once or twice a week, to help some poor people.

As he was approaching the door of his home, Zhang Jing saw three young people holding a stack of leaflets and distributing them there. Two women and one man. One of them was a girl with a round apple face and shoulder-length hair. She was not stunningly beautiful. But she was full of energy and friendly, and she smiled and said hello to the residents who were walking by her from time to time. People who walked around also gave her kind greetings.

"Sister Yuzhu is here! Sister Yuzhu is here! Sister Yuzhu is giving out candy!"

Before Zhang Jing could reach the front, a group of children rushed over from behind him, rushing to get in front of the round-faced woman.These are all children from nearby residents, the oldest is only 6 to 7 years old. They are all dirty, some are barefoot, and some have no clothes on at all.

"Get in line, everyone has something... Tiedan, you are not allowed to jump in line, you won't get any candy if you jump in line!"

Most of the little hands that were stretched out were dark, but the girl didn't show any impatience at all. Instead, she used magic to pull out a bag of candies, and asked the children to line up, while smiling and adding to the candy. Everyone put three candies in their hands, looking like a child king.

The children who took the candies thanked the girl in a hurry, and then ran to play one after another. It was not until all the children had finished receiving the candies that a child who ran at the end stumbled to the girl.The child looked to be at least four years old. It seemed that he fell because he was running too fast. His face was covered with mud stains and he looked like he was about to cry.

"Oh, don't cry, little glutinous rice. My sister left you... um... five grains!" The girl knelt down, wiped the stains on the child's face with her sleeves, touched his head with a smile, and then As a surprise, I put five candies in his hand, which immediately made the child burst into laughter. He pushed a candy away and stuffed it into his mouth, while mumbling a thank you to his sister.

Zhang Jing is no stranger to these people. This is a public welfare organization established by some young people to help the poor fight for their work rights. The young round-faced girl is a newly graduated trainee lawyer named Miao Yuzhu. The founder of this charity organization.The other members of her team should be junior students from her university who were recruited by her to do charity work.

It should be said that this organization has done a lot for the poor people here, including asking for back wages, seeking compensation for people injured at work, demanding improvement of poor working conditions, etc.Therefore, the poor people here generally have a good impression of these young people.

Zhang Jing knows that the life of the poor here is very difficult compared to previous lives. Many people's monthly income is only about 500 yuan.In addition to the general lack of various labor security regulations and minimum wage rules in the world, another reason is that the world's education levels are extremely polarized.

Although in this world, the state also subsidizes education, relatively cheap public schools lack various resources and cannot compete with those private schools that promote elite education in terms of teachers, teaching materials, courses, etc. Therefore, most children of poor people In public schools, they can only play "happily" until they graduate from junior high school, and then they drop out of school to work. In fact, what they learn in school is just literacy. Some people are even unable to perform more complex four tasks without a calculator. Operation.

However, this level of education makes it impossible for them to undertake jobs with high technical content and relatively high salaries, and private school tuition fees of 10,000+ hundreds of thousands are not something they can afford.This also leads to the fact that the proportion of Jokhang University students in this world is much lower than that of Hua in the previous life.

In this world that has entered the aerospace age, a large number of laborers have become a marginalized population due to education, and most of them can only work part-time in low-end positions to make a living.At the same time, their job opportunities are also being squeezed by technological changes such as evolving robots.

As far as Zhang Jing knows, this is not only a problem in Dazhao, but also a social problem faced by countries around the world.
