The way/s it is done should be a well-kept secret; and should not be divulged with outsiders like this.
I would urge insiders not to divulge this, and not to talk about it too much; so that it does not become a hot topic and it gets to the ears of the authorities.
OK, fair enough. I guess I should just take the job and then FIND OUT if it is possible to transfer my money to my home country, or if I will have to retire in China.
