Every day I just want to hold the fourth master's thigh tightly

Chapter 1546 Growth
Gu Youran knows a little about the "Huang Yu Quan Pan Tu".

The priest Li Dequan was talking about should be Bai Jin.

It was in the 47th year of Kangxi. Bai Jin was ordered to lead a team with Lei Xiaosi, Du Demei and others to start from the Great Wall to measure the gates, forts, nearby fortresses, river valleys, and water flows of the Great Wall.When they returned to the capital, they brought back a map about fifteen feet long.

Later, Fei Yin and others joined.This time, Bai Jin and others led a team to survey and map the west of the Great Wall, that is, the provinces of Shanxi, Shaanxi, Gansu, and Hami, Xinjiang.The rest of the missionaries were also sent to various provinces to measure and draw the "Huang Yu Pan Pan Map". Bai Jin and others also participated in the final compilation work, which took nine years to finally complete.

After being approved by Kangxi, it was drawn up in 1718 as the "Huangyu Quanpan Map" and the map of each province.This is the world's first geodetic survey completed on such a vast territory.In this measurement, the unit of length was unified, and it was found that the length of longitude was different, which confirmed that the earth is oblate.

Although the summary is wrong, it is also a great progress for the world. However, in today's Qing Dynasty, things are ahead of schedule.

Eggy frowned slightly, looked at Eniang reluctantly, and walked away with her head turned back three times.

Er Niang's gentle and loving eyes made him relax, but at the same time, many regrets grew in his heart.

He knows that this feeling is called growth.

Huang Mafa once told him.

He is a boy now, he needs to learn to be strong, to know how to make the most correct choice, to be decisive, to be ruthless and cruel to himself.

This is not the first time he has separated from Er Niang.

But this is the first time he feels that he is really different from other brothers, other elder brothers.

In addition to enjoying the honor and preferential treatment that no other elder brother can enjoy by Huang Mafa's side, he also realized the difference that any child would want to reject.

It seems... this is parting.

This is what Huang Mafa said, when sitting in that position, how much glory and brilliance he enjoyed on his body, and how much darkness he had to bear for those who worshiped him.

The glory of that position is given by others, but the person sitting in that position must have a strong control to give up what he shouldn't be greedy for himself.

Let yourself become the god that everyone admires and will never let them down.

Eggy's immature face gradually became wise and calm, and in his clear eyes, the principles that were once incomprehensible gradually became clear when they touched something in a certain period of time.

He is growing up gradually.

Growing up is painful.

But it is also a process that everyone must go through.

Eggy knows that although he is very young and weak, he will work hard to grow up.Otherwise, how could he protect the old and weak in the future like Ama and Er Niang protected him?

……

Qianqing Palace.

It was the first time for Eggy to see so many foreigners gathered together, she was quite surprised.

Because Erniang can speak many languages ​​and likes to tell him strange things, so when he saw these people with big noses, deep eye sockets, and even blue or green eyes, and heard the strange words they said when they communicated, He just raised his eyebrows slightly in surprise, and was not frightened.

When Grandpa Kangxi saw his favorite grandson coming, he kindly waved him to come over.

The "Huangyu Quanpan Map" has been spread out on the ground.

It was the first time that such a thing was shown in front of his favorite future prince, and it was very educational.
