When did Liu Bowen go to Zhu Yuanzhang?

Liu Bowen and Zhu Yuanzhang are both famous in history. Although there is suspicion, intrigue, calculation and distrust between them, they are resourceful and talented. In troubled times, they will clean up the famine and make great contributions to the reunification of the Central Plains!

There are many explanations about why Liu Bowen defected to Zhu Yuanzhang in history, which is probably to flatter the two people, and it is a historical necessity to get together! In fact, according to the present situation, Zhu Yuanzhang is not the best destination for Liu Bowen. Liu Bowen was not only a serious scholar, but also an official in the Yuan Dynasty. Even analyzing the rebels at that time, Zhu Yuanzhang was not the most powerful one!

There is a folk legend about why Liu Bowen traveled all the way to Nanjing to defect to Zhu Yuanzhang!

At that time, Liu Bowen had lost the information of the Yuan Dynasty and wanted to find the next boss. But at that time, the world was in chaos, and countless people claimed to be kings. Who should he go to? Liu Bowen, with a big heart, hesitated between Chen Youliang, Zhu Yuanzhang and Zhang Shicheng! Finally, in desperation, Liu Bowen found a fortune teller who was very accurate at that time, called Lu, and asked himself who he should help!

In fortune-telling, banxian is obviously a little higher than Liu Bowen. At that time, after hearing Liu Bowen's question, he didn't speak, just pointed to the crack of the door and stopped talking! How clever Liu Bowen was. Although he didn't understand what it meant at that time, he didn't ask again. He knew it was a secret, but just a nudge!

When I got home, I realized that Liu Bowen saw the sun on the horizon through the crack of the door. The sun in the crack of the door means Fengyang, and Lu means to go to Zhu Yuanzhang who came out of Fengyang!

This story must be interpreted by future generations, but for publicity, neither Zhu Yuanzhang nor Liu Bowen denied it. Why does such a secular legend at least prove the legitimacy of his succession to the throne?
