No matter what the difference is, you can do as I say, whether it is nourishing yin or strengthening yang, you can use it ~

You can press the inner thigh with your thumb before going to bed every day. Don't be afraid. If you feel sore, it means something is wrong. There are spleen tendons, liver tendons and kidney tendons in the inner thigh. No matter which one is pressed, it is good for nourishing yin and strengthening yang. The first is spleen tendon, then liver tendon, and finally kidney tendon. Press the thigh twice ~ and then press Sanyinjiao.
