Many codes of behavior revolve around young people showing respect to older people. Like in many cultures, younger Chinese individuals are expected to defer to older people, let them speak first, sit down after them and not contradict them. Sometimes when an older person enters a room, everyone stands. People are often introduced from oldest to youngest. Often, younger people will go out of their way to open doors for their elders and not cross their legs in front of them. The older you are the more respect you are expected to be treated with.
