1. When getting a haircut, do not say 'cut short', do not say 'just cut it casually', do not say 'cut it like this hairstyle'. Moreover, before cutting, you must first ask 'the price'. 2. Never answer your phone immediately. Especially during work hours, if your boss calls, do not pick up right away. It’s best to wait about 10 seconds before answering. 3. The 'bed' where a couple sleeps should never be shared with anyone, not even 'parents' or 'in-laws'. 4. When buying pork, try not to buy from stalls under 'warm light', and try not to buy 'the meat around the pig's neck'.
