I study in Yanda University. There is a public bathhouse in Shandongbao, opposite Yanda University. There is a small beauty salon for Dr. Yao on the second floor, which has acupuncture. Very cheap, one month 100. If you hand it in together, you can go to 200 yuan in three months. This is the cheapest I know.
By the way, I don't recommend acupuncture, because I have tried it myself, and I lost weight quickly in the first two weeks, but because I have to control my diet, few people really can stick to it. There are many examples around me, all of which lost money and then rebounded quickly.
