I made an appointment with an expert clinic. Is it ruined to go fishing nine hours early because of an emergency at home?

Count.

You can't see a doctor in advance after making an appointment on the registration platform.

Expert outpatient service refers to the outpatient service where experts (usually doctors above the deputy chief physician) have passed the qualification examination of the Ministry of Health and passed the registration. Expert outpatient service is a high-end comprehensive diagnosis and treatment platform established to meet the needs of high-level oral medical services. The consulting room has a warm and elegant environment, strong privacy, comfortable waiting and advanced medical equipment.
