Food is the most visible cultural difference: Chinese meals are communal, Western plates are individual.
Communal Dining
Dishes sit center and everyone shares, reflecting warmth and togetherness. Turn the lazy Susan clockwise and don't pick through dishes.
Individual Plates
Each person takes a portion, emphasizing personal space and moderation. Neither style is superior — just different.
Manners
Don't stick chopsticks upright in rice or tap the bowl; tap the table lightly to thank someone pouring tea; hosts often serve food to show hospitality.
Paying
Chinese diners often rush to pay the bill as goodwill; AA (splitting the bill) is increasingly common among young people. Go with the flow.
