Wall-like high rises block the sunlight from reaching indoors and weaken air ventilation and as such, we usually feel hot and humid on streets. In contrast, it appears that all our needs are satisfied in shopping malls while it sounds so difficult to find a tranquil and refreshing park for relaxation.

Shark fins are common in Chinese wedding banquets. Because of years of high demand and over fishing, many species of sharks are threatened to extinction.
