While serving someone a bowl of rice or noodles, you might insert a pair of chopsticks in the middle to make things convenient for the person. However, you will not be thanked for your good intentions, because such behavior is regarded as a mark of disrespect for the person. Why? Inserting the chopsticks in the middle of the rice bowl is similar to the placing of a burning stick of incense in the center of a burner while offering sacrifices to the dead.
往往是出于好心帮别人盛饭时，为了方便省事把一副筷子插在饭中递给对方。被会人视为大不敬，因为北京的传统是为死人上香时才这样做，如果把一副筷子插入饭中，无异是被视同于给死人上香一样，所以说，把筷子插在碗里是决不被接受的。
