First, the ugliness of Zhu Yuanzhang in Qing Dynasty. There is an old saying in China that "the winner is defeated and dies". During the Ming Dynasty, the Jurchen people lived in fear and were often bullied by the Ming court. They were almost ordered to exterminate by Zhu Jianshen, Ming Xianzong. Therefore, the Jurchen nationality has always been very dissatisfied with the rule of the Ming Dynasty and has a lot of grievances. Later, the development of the Jurchen nationality was slow, and the idea of replacing the Ming Dynasty came into being. Therefore, after the world was ruled by the Qing Dynasty, the rulers would definitely vilify Zhu Yuanzhang to extinguish their anger. Therefore, the portraits of Zhu Yuanzhang handed down are grotesque.
Second, prevent assassins from assassinating. There is a saying in the book Seven Manuscripts: Zhu Yuanzhang is suspicious by nature. After he became emperor, he was worried that an assassin would come back to assassinate him, so he found many painters to paint his face strangely, and then sent people to spread these portraits so that the assassin didn't know his true appearance. Even if he wants to assassinate him, he doesn't know who the real Zhu Yuanzhang is, and he can't find the target.
In fact, whether Zhu Yuanzhang is good-looking or ugly, there is no denying that he is indeed a very capable founding emperor. His talent and courage will not be ignored because of his appearance, and his achievements in history will not be erased.
