Kung Hei Fat Choy = Have a lucky year and win a lot of money
I went to a public W.C. in Hong Kong. When I entered a small cubicle and spotted a warning sign posted by Food and Environmental Hygiene Department.
Do not discard unwanted articles into water closet.
A water closet or water closets?
Unwanted articles, do they mean rubbish, garbage, trash, junk!
