In our life, we often hear parents, teachers and friends tell us with aphorisms or platitudes. Generally speaking, what parents and elders tell us most is that they don't listen to the old people and suffer in front of us. Teachers usually like to tell us that if the young don't work hard, the old are sad, and an inch of time is worth an inch of gold. An inch of gold cannot buy an inch of time. Tomorrow is another day. There will be so many tomorrows that we can't afford to wait. In fact, all these words are for us to work hard and not live up to the famous aphorisms of good times. Generally speaking, for a friend, it's usually a matter of knowing the horse power for a long time and seeing people's hearts. One hero, two gangs. Three people are United, and their profits are broken. Words like these generally refer to whether your friends are good or not, or whether your friends can help you.
