You are always a “Lao Wai”
The expat will have to renew working contract every 3-4 years, and this will be subject to everything on the good terms. (You are seem not giving troubles both in company and outside, you score all your checks, and etc..) yes, the eyes are watching you, everyday, everywhere.
Plus, you will be enjoying all the hatred and contempt as a “Lao Wai” in the cockpit, and you will never be one of them.
