I assume we are talking about experienced commanders. As professionals I am sure that prior to taking command of their jet they would be adequately prepared. Most of the info required should be in the company ops manuals and in Jepps. As far as Chinese ATC goes no one understands them anyway, after been there a few times you just know what they are going to say next.
There is a big difference between assistance and holding one's hand.
