Don't pass food using chopsticks!
Although chopsticks are probably one of the most useful utensils you will every use, there are some manners that you should learn about them prior to using them. The most important rule is to never pass food using chopsticks. This is done in funerals to pass the bones of the dead. Therefore, if you need to pass some food to other people, either do it for them by bringing their plate over or put the food down on a plate and use another pair of chopsticks to move it to the designated area.
