When we meet people for the first time, we usually say “ hello ”, introduce ourselves, and then shake hands. Sometimes, we give others small gifts when we meet. When it's time for dinner, we wait until all the members are at table. It's not polite to hit the plate or bowl with chopsticks. We respect the old and care about the young. We don't talk with our mouths full. After the meal, we show our thanks to the host for the delicious meal.
