Go to Chengdu Huaxi Hospital to see your knees.

Where are you from? The most recommended way now is to get a health card related to Huaxi at CCB (if you have it there). This is a new account, but not only that, you can register with that card by making a phone call, without queuing, and then you must use that card for all the procedures of seeing a doctor, so you must carry it with you. In addition, it is money. In addition, many examinations may not be completed in the same day, especially CT and MRI, so you may want to consider the possibility of staying for one day or even longer. That's all. Good luck.
