When people reach the age of 8, their kidneys are full, so their hair begins to grow and their teeth begin to change. By the age of 16, the kidney qi is already very strong, the Tiangui is mature, the essence is full, and it begins to excrete.

At this time, the man's body can be described as from prosperity to decline; At the age of 64, all his teeth and hair fell off. The human kidney is the organ in charge of water and liquid, which receives and hides the essence of the five internal organs. Therefore, the functions of the five internal organs are very strong, and the kidneys can produce and discharge semen. If the function of the five internal organs has declined, the bones and muscles have become more and more sleepy and lazy, and Tiangui will dry up; Therefore, my temples will turn white, my body will be heavy, I will walk unsteadily, and finally I will not have children.
