While the article may have good points, I was once told not to burn any bridges when leaving. It is an illusion that you can change things while giving up the fight. Unless you leaving is an illusion for some other agenda.
Depends what you are leaving, sometimes it is good to make sure that going back whatever it is not an option. Having lived there for that long there will be times in the future where he will feel nostalgic need to go back, perhaps try again.. at which point he will look at this piece and know that he will never be able to run business or work in China again a good thing in this case
