In traditional Chinese medicine, you can feel the pulse in three parts: Cun Guan Chi. Where are the three pulses?

When you first hold the pulse, raise your palms together and raise the bones behind your palms, which is called closing. The one in front of the pass is yang, the one behind the pass is yin, and the yang inch and yin ruler are searched successively. The heart and liver are on the left, the lungs and spleen are on the right, and the kidneys and the gate of life are located two feet apart. The gods of souls and valleys all see Cunkou, the left is in charge of the chief minister, and the right is in charge of the chief minister's house. The male is on the left and the female is on the right. The natal life is to support the life, the male is on the left and the female is on the right. One point before the pass, the master of human life, the left is for people to welcome, and the right is for the breath. Shenmen made the decision that if the two are behind the pass, people will not be able to recover from illness and death without having two meridians.
