• Never play or point with your chopsticks.  Do not leave them standing in a rice bowl because they resemble joss sticks used in a funeral or for ceremonies for their dead.  Doing that is considered bad luck.
• It is not good to push food around the plate with your chopsticks to find tasty morsels.  Instead, select the piece you want by sight and pick it up with your chopsticks without touching other food.
• As with regular dining etiquette, it is also not good to use your personal spoon for serving from a communal plate or bowl.
• To ask for a teapot refill, lift the lid and let it hang by the cord that connects to the pot, or let it balance on the pot handle.
• Clearing of plates once a dish is finished is acceptable—it shows attentive staff.  Plates used for bones and other discarded tidbits may be changed several times throughout a meal; but chopsticks are not replaced.
• A polite way to indicate you have finished eating is to lay your chopsticks across each other on your own bowl or plate.
