It is best to be symmetrical when you are brave. Nowadays, the style of many brave people is to catch one at a time, with the tail position not in the middle and different teeth. At this time, just tie a red rope around the neck of the brave. As for the tying method, I think you can go to this jewelry website and have a look: www.bzlgl.com, the platform has a good reputation and has a very professional jade introduction. I hope you can find a satisfactory answer.
