There are many brands of plasters on the market now, which are mixed. Take old ni as an example. Old ni bought it for my dad earlier. I feel relieved after using it, and I will make mistakes if I don't persist for a few days. It is said that old ni's own agent has established several brands, and the quality is really not flattering. However, I have also used Zhongshou, which was developed by an old Chinese doctor in Quzhou, and the effect is quite good. I bought a box for my dad and put three stickers on it, so my waist stopped hurting. After almost a month, I didn't commit a crime. I hope it helps you!
