In the early stage of piling, the body will have various reactions, because people's physical conditions vary widely, so the reactions are different and the sizes are different. Tremor is one of the common phenomena. For example, the muscles of arms, legs or a certain part of the body often shake, and people can't help it. Some people think it's amazing. Why is this happening? This is actually a step of self-regulation of the body, because a certain part of the body is not smooth. It is equivalent to the phenomenon that an empty water pipe will involuntarily swing from side to side when water flows through it.
In view of this phenomenon, there is no deliberate pursuit in the process of standing. If you have deliberate restraint, you can only let nature take its course and observe it carefully. When qi and blood are connected, this phenomenon will naturally disappear and your body will be greatly improved. The specific duration depends on the individual's specific situation and cannot be generalized.
I have seen the above jitter phenomenon in the early days, but it is just an experience. If it helps, please pay attention to forwarding it at will. For health, there is no end to standing piles.
