It is said that Liu Bowen happened to be traveling when he was 25 years old, and he met Zhu Yuanzhang at that time. One sunny afternoon, Liu Bowen was walking slowly on the road when he suddenly saw the Cowherd Zhu Yuanzhang lying on the ground. Originally, Liu Bowen just wanted to go directly, but when Liu Bowen looked intently again, he was shocked, because Zhu Yuanzhang's hands and feet were spread out, forming a word "big", but isn't the word "big" combined with the pole on his head a word "day"?
After a while, the mountain wind suddenly blew, and Zhu Yuanzhang felt cold, so he turned over and curled up his legs. Liu Bowen looked intently again, and Zhu Yuanzhang and the bullwhip around his waist formed a word "Zi". This and Liu Bowen just saw the word "day" together is the "son of heaven"!
Liu Bowen thought it must be Zhu Yuanzhang's fate. What he saw just now was definitely not a coincidence, so Liu Bowen asked Zhu Yuanzhang's name and date of birth after he woke up, and prepared to make a divination for Zhu Yuanzhang. But Zhu Yuanzhang was still young. He hesitated, thinking that Liu Bowen might be up to something, but he didn't think clearly what harm he could do after giving these private information to Liu Bowen, so the young Zhu Yuanzhang told Liu Bowen the information.
According to Liu Bowen's name and date of birth, Zhu Yuanzhang's family will perish in nine years, but he will become emperor in 32 years. Therefore, Liu Bowen predicted that Zhu Yuanzhang would become a king, not only by the word "son of heaven" that Zhu Yuanzhang posed when he was asleep, but also by the divination he later calculated for Zhu Yuanzhang.
