Do
rest your chopsticks together across the lowest plate at your place
setting when you are finished eating.
-
Do
use chopsticks to pick up pieces slightly too large to eat in one
bite. While most of your food should already be in bite-sized pieces,
when you encounter something larger, simply bite off what you can and
then return the rest to your plate.

-
Don't
play with chopsticks. They are not swords, drumsticks, etc.
-
Don't
stand chopsticks up in a bowl. Standing chopsticks up in a bowl of
rice connotes an offering of food for the dead.

Don't
use chopsticks to gesture or point.
-
Don't take
something directly from someone else's chopsticks.
-
Don't use
chopsticks to pull plates or dishes closer to you.
-
Don't use
chopsticks to skewer or spear food.
-
Don't wave them
over your food or poke at your food while you decide what to eat next.
-
Don't lick your
chopsticks. (Licking one's chopsticks has a sexual connotation
--proceed at your own risk.)
-
Don't use the
ends you are eating with to take something from a communal plate.
Reverse your chopsticks and use the other ends to take something from
a dish that is being shared.
