People in Hong Kong typically have a low threshold for two things: hot weather and hot food.

Paradoxically, the overuse of air-conditioning only serves to raise the ambient temperature (i.e. creating hotter microclimate) and their penchant for what is termed "heaty" food (which causes symptoms and syndromes of excess) does exactly what spicy food does, i.e. depleting the body's reserve of yin energy which is vital to systemic equilibrium.
