February 5 1 is ok, I have seen it there, and the charge is not cheap. There are many hotels nearby. There is a street opposite No.251. After going down, go north in the middle. It's clean and not expensive. It seems to be thirty days or forty-one days. I forgot the details. I haven't tried online registration, so I'm not sure.

By the way, it seems that the professional otolaryngology department in Zhangjiakou was only available on February 5 1, and sometimes there are no experts in other big hospitals. Last time I went, I moved several places and finally went to 251.
