According to Shan Hai Jing, Mo Mu and Lei Zu both lived in a river ditch on the south bank of Hanshui River. It may be that at that time, the Yellow Emperor wanted to take the men of his tribe out to fight everywhere, and all the women of the tribe stayed here as a base, so this place was called "Daughter Country" (contained in Shan Hai Jing Overseas Xijing).
The managers of this base belonging to the Yellow Emperor tribe may be Mo Mu and Leizu, and their relationship is even so good that they live in the same room. As the head of the "girl country" base, this is obviously not forced by conditions, but they are willing to be together.

Another book, Biography of Xuanyuan, which records ancient historical legends, also confirmed the good relationship with Lei Zu. It is said that when the Yellow Emperor traveled around the world with his concubine Leizu, Leizu died unfortunately.
The Yellow Emperor held a grand memorial ceremony for her, calling Lei Zu the "ancestor god" and appointing Mo Mu as the "guardian of pottery". This is actually guarding the tomb, which is very hard work. Every year, we should keep the burial place in Leizu and organize people to sacrifice on time.
