For example: community-based health centers, elderly centers. There is also a fitness research institute, and now foot baths and massage parlors all belong to this industry.

There is also a company that sells health products. Direct selling companies like Amway and Ruxin. What else is a SPA beauty salon?

I'm not sure about the rest, and I can't talk nonsense.

I used to work in a health research institute. If you have similar questions, you can PM me.
