Is Qiqi a man or a woman?

Qi is a man. The man's name is Qi and the woman's name is Lin.

The girl named Qi Zhi is probably her parents' wish to entrust her with having a boy, or her parents want her daughter to be brave and strong like a boy. Giving birth to a son is giving birth to a child, which is generally used to wish the newlyweds an early birth, not a daughter.
