Because Xu Ma has both culture and civil affairs, he is not only knowledgeable and upright, but also loyal to the imperial court, so he is appreciated and loved by Zhu Yuanzhang. As the first emperor of the Ming Dynasty, Zhu Yuanzhang was famous for his harsh means of governing the country. He is one of the harshest kings in history, especially those who are corrupt and bend the law. But this strict man likes his Xu very much and often praises him in front of ministers.

This person is the second daughter of Ma Huanghou and the youngest daughter of Zhu Yuanzhang. When Princess Ningguo was born, Zhu Yuanzhang was in his fifties. The old woman loves Princess Ningguo very much. When Princess Ningguo grew up, Zhu Yuanzhang also carefully selected her husband and chose Mei Yin, the nephew of Hou Meisuzu in Runan.

Main was born in a bureaucratic family. She loved reading since she was a child, and she often worried about her country and people. When I grow up, I will be an official in the DPRK, which will be more honest and clean. Mei Yin has always been dismissive of the flattery of some North Korean officials. After marrying Princess Ningguo, Mei Yin became a student in Shandong, in charge of the study and examination of students all over the world. This position is equivalent to the current director of the Education Bureau. Zhu Yuanzhang handed the important task of selecting talents to Mei Yin, which shows that he is valued.

Mei Yin lived up to Zhu Yuanzhang's expectations. During his tenure, he was fair and strict, and all the imperial examinations he presided over were open and fair. No official has ever taken bribes, which makes Zhu Yuanzhang trust him more. Before he died, Zhu Yuanzhang also issued a secret edict to Maine, ordering him to assist the new king Zhu Yunwen, and Maine always fulfilled his duties. When Judy stood up and resisted, he resolutely refused to retreat and was finally pushed into the river and drowned.
