Personally don't have good impression of China people too. Been
there before. Rudeness and about those scamming cases seem to be
more prevalent in the city areas instead. I guess they really do
everything they could to earn that extra bucks. I guess this is
more of a cultural issue. I used to read up somewhere that chinese
are pretty superstitious about helping people because they believe
that it'll bring troubles upon themselves. I'm not too sure if this
superstition really exist since I myself am a chinese (abeit
Singaporean Chinese) but I don't seemed to remember something like
that.
After Chairman Mao came into power, seemed that he expects courtesy
from the people as a mean to encourages foreigners to commence
trade/relationship building. That's when things started to change a
bit.
Can't actually quote the sources from anywhere, since it's based on
memory. But anyway, the bottomline is that opinions can differ due
to cultural influences. For all you know, picking up a coin for
them is more like a nosey act. Or perhaps, they have some grudges
with us foreigners cos we so-called stole their jobs when we go
over to their country, just the same as how we Singaporeans would
think when foreigners come over Singapore, being highly paid and in
high position.
Actually did met some really polite people over there. Don't quite
remember the province, but it's home to some Buddhist ground. They
got a monastry-operated inn there too, where they hire ordinary
people (not monks) to run the inn. Remarkable. Would love to go
there again. That too, is influence, through religion.
