Teacher of Tang Dynasty, Started the Industrial Revolution

And you fucking talk about the round sky and the square earth. Are you really ignorant and incompetent? Are you still showing off at this level? TMD The round sky and the square place refer to the orientation. Because the sky is round, we cannot determine the southeast, northwest, and northwest through the sky, so we need to use the earth to determine the orientation and the stars to determine the southeast, northwest, and use this to understand the world. Is this wrong in ancient times? When the sun rises, it is in the east, when it sets, it is in the west. The Beidou is in the north, and the rest is south, isn't it? With the orientation, observing the movement of the sun, and after summarizing and calculating, we have the ecliptic. With the ecliptic, we have the solar terms. Using the solar terms to guide agricultural production has always been an important way for us to continue our inheritance. Can you understand that? As early as the Jin and Southern and Northern Dynasties, we have known about the polar day and polar night in the "Zhou Bi Suan Jing". In the Tang Dynasty, a group of monks measured the length of the equator. Then in the Song Dynasty, Shao Jiu'an and others observed the stars and made calculations. In the Yuan Dynasty, Zhu Shijie's "Si Yuan Jade Mirror" and then to Li Shanlan in the late Qing Dynasty. We have known that the earth is round and spherical since the Southern and Northern Dynasties. Are you still showing off? Forget it, the more you read, the more angry you become, you are uneducated and ignorant! You haven't even learned your own knowledge, and you still teach others? Unimaginable.

This book is very similar to Xiaoyao Little Scholar, except that the protagonist behaves very childishly and thinks of ancient people too simply.
