Method 2: Make an appointment in official website, Huaxi Hospital, which is also slow.
Method 3: Go to Huaxi Hospital to get a medical card (a few dollars). You must have a medical card when you see a doctor in Huaxi Hospital, and then register after you do it.
The first three methods are difficult to get the expert number because there are too many people and too few experts.
If your illness is urgent or serious and you want to get the expert number quickly, you can find a ticket seller. They have the right to get the expert number, that is, charge (100 ~300), but they can get the number for you at the price of 100%.
Also, if you want to see a dermatologist, I suggest you go to the Institute of Dermatology. Their dermatology department is better, and other departments only go to Huaxi.
