Here I want to talk about Zhu Yuanzhang first. He is neither cruel nor kind. This may be the reason why people are imperfect. He instructed civil servants and military commanders how to do things, including Li Shimin, and his subordinates worked very hard. After years of hard work, they ended Meng Yuan's rule, unified the whole country and established a new country, the Ming Dynasty. His army has strict discipline and won the trust of the people. However, in the later period, he somehow killed many heroes, such as Liao Yongzhong, who was the first to be killed. He made meritorious deeds in many battles, and then some people like Li Wenzhong and Xu Da died. The disadvantage of Li Hongzhang is that he signed many unequal treaties, which brought shame to our country and a lot of losses to our country. Cao Cao's contribution lies in unifying the north and defeating Wu Heng, but it is very wrong for him to hold the son of heaven hostage to control the princes of the world.
Talking about these historical figures now, I feel quite powerful. Generally speaking, they are capable people. Sometimes it's really hard to be a good person, because you have to be a good person all the time. Once one day you do something bad, everything you have done before may disappear, but bad people are different. When people around you get used to it and find that he has done a good thing, they can change others' views.
