There are two versions of the birth legend of Laozi in history:
First, Laozi's mother, Lee, was pregnant for 81 years and gave birth to a boy. The boy was born with white eyebrows and white hair and a white beard. Therefore, Li gave him the name "Lao Zi". I can speak when I was born. He pointed to a plum tree in the yard and said, "Li is my surname."
Secondly, according to records, Laozi was born in the Spring and Autumn Period. Laozi's mother, Lee, gave birth to Laozi during childbirth. When she was about to die, Lee cut open her stomach with a vegetable knife and left her last words, hoping that her children would benefit the whole life. In this way, Li went, but Lao Tzu survived.
