First of all, there is no best hospital, only the most professional hospital, or other hospitals can not eat.
Dayun Hospital (First Affiliated Hospital) is better in gynecology, surgery and ENT.
Workers' hospital (attached to the Second Hospital), burns, skin, is better.
Cancer Hospital (Third Affiliated Hospital), if this is not explained, all tumors will go there, which is cancer.
The Kunhua Hospital in my memory is the best in ophthalmology.
Yan 'an Hospital, I forget who said that the heart is better, especially heart bypass.
I only know part of it. I suggest you choose a hospital according to your illness. You'd better ask someone in the hospital.
