There are
some FT's though who like to denigrate other FT's. The favorite slur is usually
"drunks" or "womanizer" and the there are others

It is the oppressed minority syndrome. As FT's are poorly paid and treated badly in China, they therefore tend in general to become very cautious and defensive around new foreigners/FT's they meet, as they are afraid they will upset the apple carte, so to speak, or are somehow a threat to the existence of the older or more long term FT in China. This has only got worse post 2008 with rising nationalism in China, and the downturn of the economies of the west.

In my latter years in China, I tended to shun all contact with FT's, as I found it to be a waste of time and just concentrated on getting out of there as much as I could, which I have done. Wouldn't go back for adam now.

Good luck
