First of all, you can search the portrait of Zhu Yuanzhang on the Internet. You will find that there are two different styles of Zhu Yuanzhang's portrait, one is the "pig waist" face just mentioned, and the other is the portrait with normal facial features. Why is there such a contrast? The reason is related to the feudal ethics thought at that time. Zhu Yuanzhang is the son of heaven in cloth, born from humble origins, in order to improve his birth. Let the people believe that his throne was granted by imperial power. So let the painter draw a face portrait that looks like a "pig kidney" according to the image of the dragon. There is another reason related to the Qing people. After the Qing army entered Shanhaiguan, Zhu Yuanzhang's appearance was deliberately vilified in order to consolidate his rule.
Secondly, none of Zhu Yuanzhang's sons looks like the portrait of Zhang Chou. According to Zhu Yuanzhang's descendants, Zhu Yuanzhang's true appearance is not ugly, so Zhu Yuanzhang will never be a pig's waist and pig's face.
Finally, we can judge whether Zhu Yuanzhang is a pig with a waist and a face according to Ma Huanghou. When I was a child, Ma's position was not as good as Zhu Yuanzhang's, and in feudal society, it was very important to be suitable. If Zhu Yuanzhang is ugly, how can Miss Ma like an ugly, poor and lowly person? Therefore, there is only one possibility, that is, Zhu Yuanzhang is not ugly, so he will please Miss Ma and her father-in-law. Generally speaking, Zhu Yuanzhang is not a pig waist and a pig face.
