English and Chinese in the air

There’s no way I can follow the Chinese here, but this video seems to be about Air China pilots unable to communicate with English speaking air traffic controllers. I’ve never flown them internationally, but I have found there to be a lot of English speaking flight attendants on Air China, China Eastern, and Hainan Airlines within China. It’s a little bit disturbing to think that passengers might be better accommodated than ground control on international flights.
