Cao Cao succeeded in population migration while Yuan Shao succeeded but Sun Quan failed.

Do you want to ask the reason why "Cao Cao succeeded in population migration while Yuan Shao Shi failed but Sun Quan Shi failed"?

Cao Cao paid more attention to the development of agriculture than Yuan Shao and Sun Quan, and valued talents to govern the country. Therefore, the people's life in Cao Cao's ruling area was relatively stable, and Cao Cao was located in the north, which had been developed for a long time, and was the most popular in the country at that time. Many factors such as being an economic center gave Cao Cao an advantage in population migration. In addition, Cao Cao was also a capable person, so he was more successful in population migration.

Speaking of Yuan Shao, Chen Shou's evaluation of Yuan Shao is as follows: he is generous on the outside and taboo on the inside, he is fond of schemes but cannot make decisions, he has talents but cannot use them, he hears good things but cannot accept them, he abolishes his direct descendants and establishes concubines, he sacrifices rites and worships love, but his descendants are embarrassed and the country is overturned. This is not unfortunate. . In the past, Xiang Yu betrayed Fan Zeng's plan and lost his royal position; Shao Zhi killed Tian Feng, which was even more serious than Yu Yuan. Cao Cao evaluated Yuan Shao like this: I know that Shao is a man with big ambitions but little wisdom, fierce appearance and courage. Thin, restrained but little power, many soldiers but unclear divisions, arrogant generals but inconsistent government orders, although the land is vast and the food is plentiful, it is enough to serve me. Poster, you can see from their comments that Yuan Shao is very likely to be in power. The population migration failed.

Speaking of Sun Quan, Sun Quan made significant contributions to the development of Jianye and the entire Jiangnan region. He took many measures to encourage the development of production. He "personally took over the land" and converted the eight cattle used for driving into plow cattle to show his promotion of agricultural production. He also ordered to prohibit officials from recruiting peasants for corvee service when they were busy at home, so as to ensure the production period. They also built water conservancy projects, dredged and expanded the Qinhuai River waterway, and opened Gangdu, Yundu, East Canals, tidal ditches, etc. At that time, Jianye City had thousands of skilled handicraft workers engaged in silk weaving and smelting production. Sun Quan also developed the maritime industry, sending generals Wei Wen and Zhuge Zhi to lead tens of thousands of troops to Yizhou (today's Taiwan Province). He also sent envoys to the Liaodong Peninsula and Hainan countries, and some envoys went to Goguryeo and Funan (today's Cambodia). , Linyi (now central Vietnam) and Nanyang Islands and other places. In 247, Jianchu Temple was also built for the Kang Senghui of Western Region monks, which was the first Buddhist temple in Jinling.

The poster thinks that Sun Quan was a wise king, but why did he fail in population migration? I think that Sun Quan’s ruling area was in the southeast of our country, and the southeast of our country at that time was still an area that had not been developed on a large scale, so people at that time He is not very optimistic about the southeastern region, and during the peak period of population migration, Sun Quan was not very strong and unstable, so he was not as successful as Cao Cao in population migration.
