A friend posed the question to me a while back. Why does Chinatown stink so bad? Is it something inherant to Chinese (not to care about hygiene)? Is it bad habit? Is it selfishness? Do they have higher tolerance?
Being Chinese myself, the question bothered me a little. And I probably won’t ever come to a good conclusion. But my intuition is that it is a combination of habit and selfishness. Habit because if you grew up in a less hygeinic environment, you will adapt to it. The same way you adapt to foul smell after being immersed for a few minutes. And selfishness because if no one else is keeping the street clean, why should I? It is more convenient to litter.
I recall the “Keep Hong Kong Clean campaign”, which spanned acrossed multiple decades. There was the “don’t litter campaign”, the “don’t spit” campaign, the “don’t buy hawker food campaign”, and then “clean up Hong Kong campaign”. They were succesful. So no, I don’t believe this is anything genetic or culturally related. Just a matter of the environment one grew up in.
Here are some posters from the HK campaign:
