Extended information:
Zhuge Liang’s open legislation and fair law enforcement were different from the feudal legal thought of the same era. During his period of rest in Hanzhong, Zhuge Liang took advantage of Hanzhong's economic conditions and took a series of effective measures to develop production according to local conditions, which basically solved the military resources for the Northern Expedition. After Zhuge Liang's death, the Shu Han army retreated, and the Wei army returned. In the Shu camp, "I got a lot of books and grain from him".
This just illustrates the effect of Zhuge Liang's dismissal of soldiers and farmers, and the implementation of military garrison farming and warfare. When the local people live a better life, they can attract more people, allowing the vast and sparsely populated Hanzhong to develop again, and gradually achieve a virtuous cycle of more people and more food, so that the people can "live in peace and enjoy their jobs."
