Small-scale medical centers first need a license from the Health Bureau. The scale you mentioned can only be used as a black clinic.
It is difficult to get a general license now. My friend spent 40 in Guangdong. Tens of thousands of people still refuse to sell. You can tell by looking at the price of the license that your scale is not directly proportional to the cost, not counting the industrial and commercial license and the management fees of the urban management.
