It mainly depends on what you are looking for. If you want to get checked, I suggest you go to the Medical University. After all, the instruments there are the most advanced in Nanning. The price will not be too cheap, but it will not be sky-high either. If it's a general hospital, you might consider going to the First People's Hospital. I've never been there, but it's relatively cheaper than the medical hospital.

Personally, if you have a serious illness, you should go to a medical university. Although the fees there are a bit more expensive, at least the treatment is pretty good.

In addition

If you are looking for gynecology, it is recommended to go to the district maternal and child hospital, basically all are female doctors

If you are looking for bones, it is recommended to go to the orthopedics hospital

If you want to see a traditional Chinese medicine doctor, go to the College of Traditional Chinese Medicine

Also

Don’t go to the ethnic hospital, the doctors there have bad medical ethics

Don’t go to the district hospital, and Expensive and bad attitude
