In 1344, when Zhu Yuanzhang was 16 years old, within three weeks of May and June, an epidemic, accompanied by summer locusts and drought, killed most members of his family - his father, mother and the married eldest brother who was still living at home. He had to live a meal and be a monk. However, he rose from a poor and uneducated peasant family, and then ascended to the throne of emperor and became the founder of a new great dynasty. He did some good things for the people, and also did some bad things. For example, Zhu Yuanzhang built houses for the poor, and he killed the heroes who had fought with him. He was indeed a beggar emperor.
