History live broadcast: My audience is the ancestors

Chapter 272 Lighthouse
I didn't think about using this one first: Yu Chuan Chi Su, Hong Yan Chuan Shu, Blue Bird Chuan Shu, Huang Er Chuan Shu. Why are they all animals?
Who in the clouds sends brocade books: And they are not very reliable! The most reliable one is flying pigeons to pass the message!

My charming and short-lived ancestor: you mean the food on my table?

I can’t sleep at night (Guan): Hahahahahahaha! Outrageous!

Nian Nian: How do you say that sentence? Butler, tell the fourth child that I want to eat pigeon tonight!

Yu Yusning: Hahahahaha! Upstairs, is your surname Gao? Why are you talking so madly?
Don’t let the world grow old: I agree! The person above suggested a strict investigation, it doesn’t look like the acting!

My charming and short-lived ancestor: But what if this yellow ear reminds me of a yellow dog? Oh my God, you died so miserably!
Note that this woman is called Xiaomei: There were two reformers in Da Qin, one was a quintile and the other was a quintile.

The pig is coming to the bowl quickly: Shang Yang & Li Si: Are you polite?
Who in the clouds sent a brocade letter: I actually don't feel pity for Li Si. He is the Prime Minister of Qin Dynasty, and Li Tingwei, who is less than one person and more than ten thousand people. He was born for power, so why does he need pity?
Yu Qi: Agreed! The charm of Li Si is that he will do whatever it takes to achieve his ideals, and he also realizes his ideals. In his plan, Hu Hai should continue to listen to him and let Da Qin go further. In fact, Da Qin did go a step further and lost directly.

My charming but short-lived ancestor: Indeed, after all, Li Si will do whatever it takes to get power, and what Ying Zheng lacks most is power. What should I do if I get bumped inexplicably?
Yuan Zhixu: Hahahahaha, I mean you fellow scholars shouldn’t be too outrageous, okay?

Kick the lame man's good leg wildly: Agreed! And Li Si's success is obvious. After all, even our current regional divisions have the shadow of the county system!
I can't sleep at night (Guan): Moreover, the emperor system established by him and Ying Zheng has influenced later generations for two thousand years!
Who in the clouds sent me a brocade letter: Agree! How do you say that? Later emperors only modified and modified the system established by Ying Zheng, but no one jumped out of this framework!

I didn’t think about using this online name first: Agreed! And the one who jumped out was also a great man!
Wudu refused: Woo woo woo woo, I admire the martyrs!
Qin Dynasty
Ying Zheng looked at the sky and thought of Li Si, who was still recovering from illness. A rare smile appeared at the corner of his mouth.

Xiao He:? ? ? What are you going to do?
He looked at Liu Bang and took a sip of water, and said: "No matter how powerful Li Si is, it is a thing of the past. You are the only one Nai Gong should cherish."

Moreover, Li Si is a smart man.

He suddenly looked at Xiao He and asked, "Xiao He, who do you think is more powerful, you or Li Si?"

Although he didn't know what caused his majesty's madness, he had asked the question, so he had to give an answer.

What he doesn't want is much, just the power under one person.

He can afford it, and He can also bear it!
So why didn’t Brother Zheng kill Li Si?
Because Li Si was so important, many of his policies were more beneficial than harmful to Da Qin.

Xiao He organized his words and was about to answer when he saw Liu Bang waving his hands to stop him from speaking.

He doesn't fall in the same place twice.

He is an extraordinary person who can break out of a system that has lasted for more than two thousand years.

Liu Bang looked at the sky with a rare smile on his face.

Xiao He wanted to roll his eyes, but for the sake of his own life, he said: "Your Majesty is wise!"

Xiao He:? ? ? What the hell?

However, he was very interested in the great man that later generations would say.

Liu Bang laughed loudly and said, "Nai Gong also thinks Nai Gong is a wise man. After all, Li Si cannot be used by Nai Gong."

Xiao He, Xiao He really wanted to curse.

But Liu Che was different from his great ancestor. After all, he didn't pay much attention to the literati. His favorite minister was Wei Huo!
Liu Che just smacked his lips and said: "Zhongqing, when did I have such ministers? These ministers are really troublesome!" Wei Qing cupped his hands and said: "Your Majesty, the ministers now are also very good. "

Liu Che expressed his disapproval and said, "None of them can worry about it. It's better for you and Qu Bing."

Wei Qing: Thanks for the compliment, but it’s not necessary!

Tang Dynasty
Li Shimin was reading the comments when he suddenly realized that the ministers below were all looking at him.

Their eyes all express one meaning: "Your Majesty, we want it too!"

Li Shimin silently saw the sky again, indicating that he was temporarily blind.

Su Yue clicked on the PPT and said: "Okay, now let's take a look at the next one - the lighthouse!"

Construction process

In about 270 BC, Ptolemy II commissioned the Greek architect Sostratus of Nidos to build the world's first lighthouse on the east end of Pharos Island, which could guide ships entering Alexandria. The direction, in turn, could become a huge symbol of the illustrious reputation of the resurgent Egyptian monarch.

The Lighthouse of Pharos thus became one of the Seven Wonders of the Ancient World.

The ancient Romans built a series of lighthouses, thus creating the earliest lighthouse network system.

The earliest lighthouse in this system was built in AD 50. The Roman Emperor Claudius ordered a lighthouse to be built in the Roman port city of Ostia.

The port originally had an old wooden ship that was 320 feet long and 65 feet wide. The ship was built with stones and cement to form an artificial island. The lighthouse was built on the island with a total of 4 floors.

The Ostia Lighthouse survived until the 15th century AD.

Later, Arabs, Indians and Chinese people also learned this method to ensure the safety of ships on the sea, and built lighthouses on their respective coasts.

The first lighthouse in Country Z was the Chongwu Lighthouse (1387) built in Hui'an County, Fujian Province with private funds.

In the 1412th year of Yongle in the Ming Dynasty (), the government built a "mound a hundred feet square and more than thirty feet high on the beach southeast of Liuhe estuary at the mouth of the Yangtze River, with smoke raised above it during the day and open fire at night" to guide ships in and out of the Yangtze River. mouth.

This is a precedent for country Z to have government-funded construction of navigation aids.

In 1858, after the signing of the Treaty of Tianjin between the British and the British, it was stipulated: "Each trading port should set up floating piles, ships, towers, and watchtowers, and they should be built at the discretion of the consul and local officials." This opened the door to the modern lighthouses of China. construction.

modern tower light
From the end of the 18th century to the 19th century, light emitters with reflectors, lens lighthouses, electric lighthouses, etc. appeared one after another.

The first gas flash lighthouse was completed in 1906.

As modern navigation equipment has become very advanced, the number of human-operated lighthouses has been greatly reduced. There are only 1500 lighthouses still operating in the world.

A lighthouse's light source, called a "lamp" (whether electric or oil-fueled), had long been lit by an open flame, later replaced by candles.
