What are the five binding methods in Bound Flowers? How exactly is it tied?

The so-called Chinese-style binding, or "bound", is a traditional binding method in China and a cultural accumulation of the Chinese nation for thousands of years. It can be done quickly, and it is extremely difficult to break free, and it saves rope. The method is roughly as follows: starting from the center of the rope, dividing it forward to the front armpit, passing through the back edge and winding the arm downward. Generally, the upper arm turns 2-3 times, and the lower arm 1-2 times (in fact, one turn of the upper and lower arms is enough) to the wrist; Hands are crossed with wrists at the back, and the rope of the lower arm is crossed and wound around the wrists twice, and the knot is completed. On this basis, there are various deformations.
