Hello

In the moving of Yin Yang exercise, it mentions at the end:
" as you finish, both hands slowly stop at the lower dantian position. For men, put your left hand in and right hand out; for women, right hand in and left hand out. Feel the emptiness in the space between the body and the hands and between both hands".

I am not sure what lower dantian position is. There's no photo & it's not in the video.

Thank you in advance.

Lower Dantian is 3inches below your navel and 2/3 inches backward. This general rule of thumb in all type chi kung

Chunyi says about the lower dantian that it's "deep in behind the navel".
