In the fifteenth year of Hongwu, Empress Ma passed away and left Zhu Yuanzhang, who was crying so hard. In late autumn, Jinling was completely deserted. Zhu Di, who traveled thousands of miles south to pay homage to his filial piety, wanted to cry to death on the spot. It was also this year, Zhu Di met Yao Guangxiao, the noble man of his life. There was also a junior brother standing beside the latter. His Royal Highness King Yan, this is the junior brother of the poor monk, whose dharma name is Daoming.
