Make friends: 1. Respect life, respect deacons and be loyal to others.

There are three friends who have benefited and three friends who have suffered. Friends are frank, friends forgive and friends listen more, which is beneficial. Friends make friends, friendly and soft, and friends will be destroyed and damaged.
