The secret has a cloud: "What does it mean to give up your strength? Water can carry a boat and overturn it. The score is very good. Give up your strength like a boat. Of course, the shed force is related to the weight of the ship and changes according to the external force when pushing the hand. More sheds are called tops, and fewer sheds are called losses. It should be pointed out that no matter how heavy the ship is and how strong the shed force of water is, every water molecule under the ship is loose, which deserves our praise and praise. Other strengths are also based on this strength. Some people say that shed strength is four or two strengths. The so-called "four-to-two-to-one-thousand-pounds" refers to the change on the basis of the minimum strength of shed force, but it does not mean that all the forces encountered are shed with the minimum strength. The minimum value is actually the best way to change, for example, 90 degrees is the most labor-saving. As for how to get out of the shed? Mainly obtained from pine, it can relax and sink naturally. In Tai Ji Chuan's training methods, from loose to soft, from soft to hard, this is actually just some meaning, but loose and soft are regular, because it has nothing to do with this problem, so I won't explain it too much!
