According to relevant public information, Ma Buyun is the deputy chief physician of the Department of Ultrasound Diagnosis, West China University of Medical Sciences, Sichuan. The weekly clinic hours are from 8: 00 am to 12 on Tuesdays and from 2: 00 pm to 6: 00 pm on Thursdays. You can hang up 50 numbers at a time, but you can't hang up many times because there are too many people to register, which can't meet the registration needs of all patients.
