How about Changchun Tongren Clinic?

You mean Tongren Eye Hospital, right? I've been there. I made an appointment online. When we arrive at the hospital, the registration fee and inspection fee are free, but only for experts in our hospital. It costs money to hang experts in Beijing, probably around 30 yuan. Last time I went, I just prescribed medicine and spent 30 yuan. I feel that it is quite formal there, and it is not for arbitrary charges!
