West China Hospital and Sichuan University merged. Huaxi Hospital has four affiliated hospitals. The First Affiliated Hospital is what we often call Sichuan medicine. The second hospital is a maternity hospital, the third is a stomatological hospital, and the fourth is an occupational disease prevention hospital. The First Affiliated Hospital is the largest single hospital in the world at present, and the Second Affiliated Hospital is the largest women and children hospital in southwest China. It should be said that each has its own characteristics, not which is the best.
