China

Chinese etiquette carries real symbolic weight: a homophone can turn an ordinary gift into a bad-luck one, and even how you eat a whole fish can read as tempting fate. Business and dining customs here reward attention to detail most visitors don't expect.

9 rules.

Present business cards with both hands

Don't sit down until you're shown your seat

Expect the man to pay, but offer to split

Don't flip the whole fish over

Never give a clock as a gift

Take off your shoes, wear the slippers you're given

Never criticize someone in front of others

Let the host toast first, and clink lower

Use three sticks of incense, never a random number
