Teacher Qin Shuyuan answered the confession question about rheumatoid arthritis. Upon inquiry, I learned that Qin Shuyuan is the founder of filial piety training company in Fengxian County, Jiangsu Province, a senior lecturer of Henan National Studies Research Association and a lecturer of Zhejiang Vegetarian Association. He said that the confession of rheumatoid arthritis is to be a vegetarian and exercise frequently. This answer is for reference only. Don't be blindly superstitious.
