Honestly just let him move there and let him find out, he has basically disowned the west thinking its a cesspool (It is but its the cleanest one on the market). Some people just need to learn about the fact of you don't know what you got till its gone and the fact that they think the grass is always greener on the other side. If he ends up in a tiger chair I would just laugh at the stupidity of him thinking moving to china was a good idea. I am not here to convince people out of bad decisions just laugh at the stupidity and ignorance of them.
