Why did most famous poets in ancient times have no descendants of their own?

Li Bai had two sons after him. The first one was Li Boqin, and the second one was Li Pingyang. The second son has no children, and the eldest son Li Boqin has two daughters, both of whom are married. Li Bai was handed down from generation to generation. On the other hand, the geomantic omen in Li Bai's hometown, with mountains and no water, high in the east and low in the west, is magnificent and lacks spirituality, which is really not a good word. However, people should be satisfied with Li Bai's 10% achievements.

Du Fu doesn't know.

Poets are unrestrained and like to travel around. How can they have time to spend with their wives? The less time we spend together, the less chance we have to have children. It used to be difficult to have a baby.
