Well, Xi 'an Jiaotong University Second Affiliated Hospital? Hehe, to be honest, I suggest you not to go. It's no use going there. A while ago, I visited major hospitals in Xi 'an, and the cost of light medicine was nearly 10,000, and the result became more and more serious. Finally, I decided to try TCM conditioning. After all, acne is an endocrine disorder, and the liver fire is too strong. Then I went to Shaanxi Provincial Hospital of Traditional Chinese Medicine and got the 10 pair, hehe. ~ ~ I hope I can help you
