1 level is the worst, 3 level is the highest
Relatively good hospitals in each level are class A
There doesn't seem to be a class B, and it's not nice to say.
For example, a hospital that is not a level 3A and meets level 3 hospital standards is just a level 3 hospital.
Tertiary A is the highest level hospital, equivalent to a five-star hotel.
But the same three A, the gap can be very big, and hospitals like this place are talking about the main direction, Beijing is everywhere three A, the grade is almost meaningless.
