Unless you are totally fluent in one of the Chinese dialects, Mike, I would suspect you have next to no chance of working in China, as ALL R/T transmissions in Chinese airspace, between Chinese aircraft & ATC, are in Chinese.
The only time English is spoken, is for comms with a non-Chinese aircraft.
To put your scenario into perspective, your request would be akin to a Chinese speaking flight instructor looking to find work in England!
I`d suggest you follow up on kwaiyai`s offer if he`s aware of vacancies in Malaysia (I`m sure that you`ll enjoy it a lot more there, too.)
