I've been in Hong Kong long enough to notice some patterns appearing in the names of Hong Kong's places. Most of the places had 角 or 灣 in them.
For example: 角: 旺角, 大角嘴, 北角, 沙頭角
灣: 灣仔, 西灣河, 銅鑼灣, 荃灣
Is there a reason why 'corner' and 'bay' are used very commonly for place names in Hong Kong? I can guess for 'bay' because Hong Kong is a harbor with coasts, quarries and bays.
But for 角, why would so many places be named after corners?
