I don't think laowai are much better at picking Chinese names. I have have seen more than one dumb foreigner to pick "Doufu" as their moniker (most likely because those are among the few Chinese words they know). I chose for my name 王义力. It's easy to write and the two characters mean "justice" and "force, ability" but my girlfriend says that when you stick them together it just sounds like the name of a brand of sausage. So I guess I'm just 王义 now.
agree. hahahahahaha
met a young guy before named himself as 金牛奶 which I totally didn't get what connection he had with milk. he explained he just liked the pronunciation of niunai.
And another interesting Greek man introduced his chinese name was 小狗
