I know there is a saying in the pile of health care in a spring called "the first seven and the last three". The so-called "first seven and then three" refers to a common name for the weight distribution ratio under the foot plate in the standing pile. "The first seven and the last three" are divided around the "Yongquan point" under the footboard. If the weight in the standing pile falls on the palm of the front foot, the pile boundary is called "the first seven and the last three"; If the weight falls on the heel behind Yongquan point, it is called "the first three and the last seven".

I hope this is what you want.
