I used what you said about Zimuqingfeng ointment. The year before last, my leg got rheumatoid arthritis because I rode a motorcycle for a long time. I saw that the advertisement of Zimu Qingfeng ointment was well done on the Internet, so I contacted them and found that Zimu Qingfeng ointment was only a black plaster processed by individuals. The packaging is ugly. To tell the truth, I have little confidence in this kind of thing. I barely posted a post, but it was a little hot after trying it, and I didn't feel anything else. I thought it was useless. On the fifth day after plastering, I suddenly felt that my legs were much lighter. Later, I ordered 8 stickers by mail, and now my leg doesn't hurt.

The Zimuqingfeng Plaster I use is a hand-made black plaster. I wonder if this is what the landlord said. By the way, this plaster is not cheap. It seems that it was 80 or 90 yuan who posted it at first. I forgot!
