The disassembly and assembly method of nine-ring chain is recursive. This is the only way, there is no other way. This is determined by its disassembly principle:
It takes 341 steps to untie the nine-ring chain. As long as you go up or down, it's all one step. The expansion and nesting of nine chains are a pair of inverse processes.
The rings of the nine-ring chain restrict each other, and only the first ring can go up and down freely. If you want to get down/up the nth ring, you must meet two conditions (except the first ring): ①. N- 1 ring shelf; ② The ring in front of the n-1ring is not on the shelf.
The process of playing the nine-ring chain is the process of satisfying these two conditions all the time.
Dismantling the ninth ring essentially starts with the back ring. Remove the front ring first and then the rear ring. The front ring has to be installed, not really removed.
