Zhu Yuanzhang became king because of what his grandfather did?

According to legend, Zhu Yuanzhang became emperor because his grandfather found a treasure trove of geomantic omen.

It is said that Zhu Yuanzhang's grandfather lived in a place called Yangjiadun. One day, Zhu Yuanzhang's grandfather was resting, and suddenly two Taoist priests (an old man and a young man) passed by his house, and their conversation happened to be heard by Zhu Yuanzhang's grandfather. Among them, the old Taoist said: I can see that this is the legendary longan, and this land is a collection of heaven and earth. If a tomb can be built here, there will be an emperor who rules the world among the descendants of the people buried here.

The young monk didn't believe it, so the old monk put a branch there and told the young monk that after ten days, the branch would surely sprout. At this time, they saw Zhu Yuanzhang's grandfather pretending to be asleep. They were going to tell him, but they didn't wake him up because he seemed to be asleep. As a result, after more than ten days, this branch really sprouted. Zhu Yuanzhang's grandfather was very happy to know, but he was afraid that others would know the secret, so he replaced the branches.

A few days later, two Taoist priests came to see the branches. Seeing at a glance that the branches had been changed, the old Taoist asked Zhu Yuanzhang's grandfather. Grandpa Zhu Yuanzhang could not hide it, so he told the truth. The old Taoist sighed: Your son could have been emperor, but because of your behavior, you can't be emperor until your grandson.

Later, before Zhu Yuanzhang's grandfather died. Ordered his son to bury him in what was then known as a treasure trove of geomantic omen.

In fact, this is just a legend. Zhu Yuanzhang became emperor mainly because of the social environment at that time and Zhu Yuanzhang's own ability.

Zhu Yuanzhang was poor since childhood and once spared cattle for the landlord. 1344, Zhu Yuanzhang entered the ancestral temple. Then the world was in chaos. At the age of 25, he joined the Red Scarf Army led by Guo Zixing against the Yuan Dynasty. 1356, Zhu Yuanzhang was regarded as the Duke of Wu by his subordinates. In the same year, Zhu Yuanzhang captured Qing Ji Road and changed it to Tianfu. 1367, Xu Da and Chang Yuchun were ordered? Drive out Land Rover and restore China? In order to call for it, the Northern Expedition ended Meng Yuan's rule in China and recovered sixteen counties that had been lost for 400 years. 1368, Zhu Yuanzhang officially proclaimed himself in Yingtianfu, changing the country name to Daming and the year number to Hongwu. After several years' efforts, China was finally reunified peacefully. ?
