This will make people feel comfortable when they talk to you. The impolite people are not welcome here and we will ask them to leave. Second, be honest. We hope that our members can trust (信任)each other. If we find that you tell lies to other club members, we will ask you to leave the club. Third, be a good listener and keep your friends’ secrets.
