1993 and 2016 is no difference as far as mannerisms of the people are concerned. That a stampede did not happen again is due to improvement in police's crowd control techniques and choice of permitted locations for large crowds to gather and move about during new year's day countdown and not any change in the psychology of the people.
So far I have yet to encounter a PRC shitting in public although I have encountered PRCs doing other things which has a higher probability of occuring and greater difficulty of avoiding and the same kinds of things are also done by Hongkies - sneezing like fucking thunder without covering mouth and nose (not limited to chow Ah Peks but much higher probability so avoid sitting or standing or walking near to chow Ah Peks), coughing loudly and like going to die like that (all Chink males of whatever age) and of course don't cover the proper or any orifice, clearing throat loudly, sniffing or snorting their fucking noses constantly (Chink teenagers are particularly prone), etc. If one takes the bus from A to B that pass through the public housing estate during morning rush hour, the vehicle becomes like a fucking zoo with all the above types of noise. However, if one takes the express bus from A to B that skips the public housing estate totally, the difference is between heaven and hell and if you hear a loud sneeze like thunder occasionally ........ 101% is by a Chink Ah Pek! Doesn't matter one bit if the fucktard is from PRC or Taiwan or Hongkie or Sinkie! Moral of the story - take the express bus and stay at least 10 feet away from any Chink Ah Pek. Females dressed classily in their twenties have an image to keep and a husband to snatch before expiry date, therefore less probability of such anti-social behaviour but not totally exempt.
Another thing - many Chinks, regardless of Sinkie, m&d, PRC, Taiwan, Hongkie or whatever else, think that one of the greatest inventions of all times is - the toothpick! Fucktards also make a lot of noise and for a long time after the food is finished using this instrument!
