Going to China (or let's be honest the USA as well) take a burner.
You know your phone will be examined so don't take it. Take what you need and no more.
If you're going to the states make sure you've no social media accounts or if you can't remove the app at least remove the account from the device.
You can use the web for your email at least until you reinstall the app.
If you going to China really you should expect to need to toss your devices when you get home or at least have them refomatted.
