Does anyone know that Gan Long's mother gave birth to eight children?

I only know that she was born on November 25th, the 31st year of Kangxi.

Accordingly, the first six words of the eight characters are: Ren Shen Renzi Wu Geng.

I don't know when she was born, and I guess you are unlikely to know. Most people don't talk nonsense about such things, let alone the queen mother.
