I find Hong Kong overtly smoggy. Bad air, too many crazy taxis, and people with no concept of Deodorant. Then again, this is unpreventable in a city of 6 million + in such a highly densely populated region. Imagine if everyone farted at once? I think the smog would probably thicken. Perhaps that is a logical explanation of why HK smells so bad. If there is so much pollution which is all kept in by the tall buildings (no air current allowed through to clear the pollution), it must create this layer of perpetual smoke that forms a saran wrap for the smells that emanate from the city (e.g. rotting garbage, people farting etc.) .Perhaps the word 'Hong' or rather, in cantonese pronunciation "heung" which means fragrant should be changed to "chou" or stinky in Hong Kong. (kong is harbor) It should be called Chow Kong. Stinky harbor.
