Those whingers and whiners are all probably brain dead. Big claims of being super pilots but are really conmen with scant knowledge of meteorology and climatology.
Hong Kong and most parts of southern China are pretty humid for most times of the year, epecially late spring, summer and early autumn. The haze is mainly due to the vapour content and coupled with some dust, visibilty becomes poor. It causes the situation to look and seem much worse than it actually is.
