2. When tying a Chinese knot, first pinch the middle position, knead the rope into three loops, then arrange the three loops in a cross, naturally put the rope without loops at the lower end, then bend the middle loop and press it on the right loop.
3. Next, turn the right ring to the left, press the middle ring and the center line at the same time, and the left end will be exposed. Then turn the lower end of the middle rope up and press it on the right ring. At this time, make sure that the shapes of other rings remain the same.
4. Then turn the left ring to the right, press it on the top of the rope turned in the previous step, and then pass through the middle ring that was originally pressed, so that there are four heads on the ring. After that, the four heads exert force evenly, and the three rings and the rope in the middle are tightened around. Then, in the same way, the four heads are tightened evenly around.
