Do not trust any russian or chinese you come in contact with.
The main land chinese for the most part are and have been indoctrinated so much that they lie, steel and graft at the drop of a hat. They will steel for their government, they will graft for their government, they will lie for their government and that may be just a side hack to their own steeling, lying and personal graft. They cheat in business, the cheat in school, they cheat each other.
It' been stamped on their genes. It is a law that every chinese any where are under the direct control of the chinese government "ccp'. Oddly the russians are pretty much the same, years of communist rule and their intellectual rape of their own citizens has take it's tole. Like the chinese 'ccp' the russian 'kgb' has done the same thing and corrupted their people so much that if they are not steel try aren't trying.
So keep mouthing the fellow traveler guide books useful fool sayings if yo wish but I would warn you to keep your hand on your wallet, wife and kids when either a russian or chinese is around.
I deal with people on an individual basis, so I base my impressions on a personal interaction whenever that is possible. If it is not possible, I resort to a group impression.
If you do otherwise, that is on you. I don’t judge you, so I would appreciate it if you refrain from judging me.
