I want to know the specific method of cupping at Sanyinjiao (not the use and benefits of cupping) but how to do it.

Sanyinjiao is the intersection of foot three yin meridians (foot Taiyin spleen meridian, foot Shaoyin kidney meridian and foot Jueyin liver meridian). 9- 1 1 in the morning is the running time of spleen meridian, 5-7 in the afternoon is the running time of kidney meridian and 9-1/in the evening is the running time of triple energizer meridian.

In fact, it is equally effective to massage Sanyinjiao at the above time.

Cupping does not have to have obvious congestion to be effective. There was no response after it was pulled out. It may be that the meridians in the legs are blocked, and qi and blood can't get together at once.

Because the principle of cupping is to push the garbage out by one's own qi and blood, it is not recommended to use this method more for people with insufficient qi and blood.

I suggest you start with soaking your feet and massage Sanyinjiao and Yongquan at the same time. Try this method first.
