This is funny, but it's also terrifying in its implications, and exactly why I will never fly any airline from any country except the United States or other English speaking countries...okay...yeah...also European airlines. That's it. China? No. Way.
The English language is the international standard for all air traffic communication. Period. If you can't speak it perfectly, then you have absolutely no business being in the cockpit of an international jetliner. Period.
The air traffic controller showed remarkable restraint in this exchange. If WWIII ever breaks out, it will be over an exchange like this when some poor air traffic controller just flips the eff out and starts screaming and running planes into each other.
