I'm not aware of Chinese authorities getting quite that draconian (yet) at the normal border entry points in Beijing, Shanghai, etc. However, I think it's still worth following the general advice that if you have sensitive data on your devices, leave them at home and use a burner phone/laptop + restore from the cloud later.
