About TCM and medicine, that is factually wrong.
If the germs are already in your body, you will only spread them [be spitting them out] and that is very selfish and a guarantee for epidemics. There is no proof that spitting phlegm is helpful to your own health.
That's why we have 365 flu seasons in China and not 2 or 3, all year round.
Trash
In parts of major cities, yes, ...but everywhere? No!
Cultural
There is nothing in Chinese culture that dictates to treat other like sh*t, quite opposite, all of Chinese sages, promote caring for other, virtues, and patience.
But that would need people to care and invest a second or a thought. But that's what I mean about socially lazy. Many Chinese complain or whine about that some Western countries are so great, when I ask them, how do you think it got there, hey all say that the president and government told them to do so. When I tell them, no! the people agreed to become a better society, they look at me like I am crazy and instead of sayin, "Hm, that is interesting. "Or, "Maybe we should try that!" or mumbling, "Maybe we [I] could start with small steps."
The answer is always, "That will never happen here!!!"
When I ask them why, I get something like : "I don't want to give up smoking." "I don't think I will walk for half a day to find a trashcan"
Then I tell them, "See, most people overseas, do!" And that is where the conversation usually ends. lol
In short: Unless HK'ers and Taiwanese are not Chinese, they are still fully culturally Chinese without all the nasty habits. Actually according to Chinese cultural standards there are closer to the real Confucian ideal, than the mainland Chinese.
Violence
I [an most of my friends and acquaintances ] have been attacked [sometimes with weapons], numerous times. And except one time it wasn't in a place where alcohol is available [a diner, bistro, in that case]. Three of my friends have been hospitalized, for several days.
I have seen numerous attacks on foreigners in the most cowardly manner.
I have been [when not responding to countless "HELLO!" ...giggle giggle...."HELLO" 's] approached in a very aggressive manner, numerous times.
I have been cursed with the worst curses and racial cussing, [so did my wife, for being with a foreigner], and told numerous times, [as well as many gokunming posters did] to leave the country immediately.
Except one incident, where we didn't help to deescalate the situation, these attacks were without provocation and targeting foreigners.
I had two [Chinese] co-workers, being robbed, one is now unable to work, after getting her head caved in with a baseball bat [or something like that] she has migraines for 50% of her days. She even thought of suicide, when the stronger pains come in.
The cops have not found anyone, although there were street cams in the area, overseeing the spot.
Club security in Kundo won't let foreigners in, usually after repeated beatings, force them to protect the Chinese clientele form bleeding laowais and the look of beaten up laowais in the vicinity of the establishment.
Oh, and a foreign friend of mine got beaten mercilessly last week. He looks like a car hit him. He said he got jumped by a few guys, walking down the street [no...not kundu]
I have more incidents, if you need to hear?
Ask your Chinese friends about incidents from burglaries gone bad, also check the daily Kunming news, and enjoy the peaceful, violence free China experience, for as long as it last.
