Taboos At Work
Shopkeepers may opt not to read a book at work because book (書, shū) sounds like lose (輸, shū). Shopkeepers who read may be afraid their businesses will suffer losses.
When it comes to sweeping, shopkeepers are careful not to sweep toward the door, especially during Chinese New Year, in case good fortune is swept out the front door.
When eating a meal, never turn over fish when you are with a fisherman as the motion symbolizes a boat capsizing. Also, never offer a friend an umbrella because the word umbrella (傘, sǎn) sounds similar to 散 (sàn, to break up) and the act is a sign that you will never see each other again.
