What contribution did Liu Bei make?

After Liu Bei entered Shu, he first relied on most landlords in Shu to stabilize the Shu-Han regime. Then Zhuge Liang's suggestion that "the west should be tolerant and the south should help foreigners" was adopted to stabilize the social order in the ruling areas and appease the people's hearts. The specific measures are: 1. Develop agricultural production. Zhuge Liang specially sent 1200 people to protect Dujiangyan (then called Du 'an Dayan), which played its role in irrigation efficiency more effectively. At that time, the yield of rice per mu in some areas of Chengdu Plain could reach 30 hectares. According to historical records, there were ditches in the fields at that time, and golden rice and millet were everywhere, which was a scene of "land of abundance". 2. Develop salt industry and handicraft industry. At that time, Chengdu "had a salt spring well at home". Brocade from Sichuan is exported to all parts of the country. "Biography of the Three Kingdoms and Wang Lian" says: "Compared with salt and iron, it benefits many people and the country." This has played an important role in stabilizing the domestic economy and supporting the Shu-Wei War. 3. Immigrate to Sichuan to develop South China. (Now it is a part of Yunnan, Guizhou and Myanmar). Shu Han broke the long-term closed state of South China and promoted the development of this area. After the establishment of the stable rear of Shu, Zhuge Liang moved 1 10,000 Qiang people to Shu, engaged in animal husbandry production, and formed a young and strong army among them, becoming a warrior teacher. The above-mentioned measures of Shu not only consolidated the political power, but also greatly enhanced the economic and military strength and stabilized the people's hearts at home.
