The main idea is to say that given a picture, each hop side has a number $0$ or $1$, each can be a simple ring on all sides $\oplus 1$, the construction scheme so that the number of each hop edge is a value, the scheme involved in the edge of not more than 5mIf the two rings in the scheme have intersecting parts, the intersecting parts do not change, and then 2 rings are merged into one ring. So there's a s
