Li Bai was a famous poet of the Tang Dynasty. His family background was unknown, so his family was never mentioned in history books. According to historical records, Li Bai's father was a wealthy businessman and his mother was a local woman. Li Bai also had two brothers and a sister. Li Bai's brothers were called Li Yun, Li Yangbing, Li Congjun, and Li He. His sister was called Li Baihua. There was no clear record of when Li Bai entered the palace. There was a legend that Li Bai had been granted the title of Prince Taifu in the middle of the Tang Dynasty, but there was no conclusive evidence for this.
