Zhu Yuanzhang compiled the yellow calendar.

Zhu Zi, the son of Zhu Yuanzhang, chose the whole family to set himself on fire. It is said that this is because his child Zhu Yuanzhang was involved in the famous Hu case in the early Ming Dynasty. As we all know, Zhu Yuanzhang attached great importance to this case, so many people were involved in this case and tens of thousands of people died. Zhu Xi was also involved in this case, which is why Zhu Yuanzhang forced his favorite son to death.

However, some people say that this matter is actually untenable, because Zhu Yuanzhang is very indulgent to his son. It was the third son who was suspected of rebellion, and Zhu Yuanzhang only gave him a verbal warning. Therefore, it is untrue that Zhu Yuanzhang killed his son because of the Hu case. Therefore, there is another folk version, that is, Zhu Xi set himself on fire because Zhu Xi's father was not Zhu Yuanzhang. Zhu Xi's real father is Zhu Yuanzhang's sworn enemy Chen Youliang.

It is said that Zhu Yuanzhang knows that his son Zhu Xi is not his own, but after all, Zhu Yuanzhang has raised him for so many years and has some feelings for each other. But Zhu Xi doesn't think so. He thinks that Zhu Yuanzhang is his father's enemy, so even if Zhu Yuanzhang has the favor of raising him, he can't live under Zhu Yuanzhang's rule. So in the end, Zhu Xi chose to burn himself to death.

But this is not all possible reasons for Zhu Xi's death. The third possible guess is that Zhu Yuanzhang, the eighth son, was so cruel that he even killed the princes in the palace at will and made some women in the palace do some obscene things, which is why Zhu Xi finally angered Zhu Yuanzhang, which led to the final result.
