How big is Sanno? How is the development space?

Sanno is quite big, has its own independent industrial park, and is a listed company, is currently headquartered in Changsha; I have a little sister to work in Sanuo, listening to her say that the company's treatment and benefits are good, cafeteria, gym, dormitory and so on are very complete, the development of space, the public company in general is very promising, or not to do this extent not? So, if it is to change jobs, you can try Sanno.
