There are more than 50 major decisions such as meridian tactics, and each major decision has several to a dozen changes, all of which belong to the esoteric biography. Besides meridian formula, it is difficult to find other manual tips on the Internet. You can find some in the book.

Let's talk about meridian formula first. The left thumb grips the fingertip of the left middle finger, and the other three fingers naturally bend with the middle finger. The right thumb passes through the ring formed by the left thumb and the left middle finger, and the other four fingers of the right hand naturally cover the four fingers of the left hand except the thumb. After holding it, the palm is inward and the position is about 3 inches below the navel. Practice starts at midnight.

Regarding the grip strength, when walking, the foot uses five fingers to exert force, and the center no longer follows the fingertip. Hands will naturally make a fist. When you walk about 300 meters, you will feel your fist make a fist naturally. You can obviously feel the swelling of the ring finger root pinched by your thumb and the feeling of blood beating.
