Zou's achievements

Zou Yisheng wrote about great wealth, talked about Hunan scholars, followed Chuanshan's "Wang Fuzhi" and pushed "Yuan", which was romantic and literary. His geography and geography works are particularly important in the world. He himself is proud of this, saying that he wants to let the world know that people who talk about land are all in the grass. In geography, he comprehensively summed up the previous experience of drawing maps with latitude and longitude, and constantly enriched the theory and method of drawing six bodies by Pei Xiu in the Western Jin Dynasty. He believes that any place has its extremely high skewness, that is, latitude and longitude, and the position of each prefecture can be determined on the map by using the extremely high skewness, which is consistent with the basic principle of measuring latitude and longitude today. Han Xun's younger brother, Han Chi, and his nephew, Shi Zhi (Zi Ziyi), were hired by Hu Linyi, the governor of Hubei Province, and used the above principles when compiling the Unified Map of the Qing Dynasty. The completion of the map is called trial, which is superior to the map of the inner hall in Kangxi of the Qing Dynasty. And his grandson Daiyu gave full play to this principle and adopted western learning, making Zou's knowledge and knowledge the best in the world.
