The basic skills of "knot" can be divided into five types, namely "pull", "pull", "jump", "shake" and "shake".

(1) Gong: Put your knuckles up, cross the gap in front of the bottom plate with your index finger, the thumb naturally rises, the middle finger, the ring finger and the little finger stick to the back side of the bottom plate, then the wrist shakes, and the first four plates collide with the bottom plate, making a beep. The work requires natural movements, one beat every half, and the speed is stable and even.

(2) Lifting force: On the basis of "lifting force", double the speed, lift the last board with the bottom plate and make a beep, and use this force to enhance the wrist strength.

(3) Bounce: Hold the knot horizontally, press the thumb on the top of the knot, and push the elbow and wrist upward to make it bounce, and also make a single "beep" sound at the same speed as the gong.

(4) Shaking force: make a knot, with one side facing outward, put your thumb on the waist of one of your brother's boards, shake your wrists left and right, and hit the first four boards with the bottom plate with a beep. When the current four chess pieces are lifted, they are bounced back by the thumb, making a "click" sound again, and so on. The first half is a "click" and the second half is a "click", so the speed is even and unpleasant.

(5) Shaking force: On the basis of "shaking force", the wrist shakes rapidly and continues to make the sound of "Wow ……", and the speed should be even, neither fast nor slow.
