Politically, Zhuge Liang, as the prime minister of Shu Han, took the lead in raising the banner of clean government to the officials, and Zhuge Liang also included clean government in the assessment of officials and implemented it as a national law, which also had a great impact on the economy, politics and culture of Shu Han. Liu Chan, the former ruler of Shu, wanted to expand the harem just after he ascended the throne, but Zhuge Liang refused Liu Chan's request to excessively expand the harem, because it would cost a lot of money for Liu Chan to expand the harem.
Zhuge Liang also set an example of honesty and uprightness in the political upper class of Shu Han. Officials of Shu State, large and small, followed Zhuge Liang's example and worked hard to love the people, which also made the political outlook of Shu Han prosperous. Economically, Zhuge Liang took advantage of the good local economic environment in Hanzhong and promulgated some measures according to local conditions, which also solved the problem of military capital needed for many northern expeditions. The most interesting thing is that after Zhuge Liang's death, the Shu army retreated hastily, and many materials were left in the camp without taking them away. In the process of pursuing the Shu army, Wei Jun found a lot of grain and grass in the Shu army's station, which also reflected the good effect of Zhuge Liang's sending his soldiers to wasteland.
Thanks to Zhuge Liang's policies, the life of the people in Han Shu has been greatly improved, and more people are willing to come to Han Shu, which has also enabled Hanzhong to start developing again and the people can live and work in peace and contentment. Some water conservancy projects built by Zhuge Liang in those years are still used by people in Hanzhong area. Officials of past dynasties also tinkered with Zhuge Liang's water conservancy projects at that time, eventually making Hanzhong a rich place.
