I only know the meaning of this sentence, which means that friends are precious. Although we can't meet each other, that feeling still exists. Ordinary people may not meet, and people will forget you. It is enough to have one or two such friends in life.

Making friends is more important than making many friends. Some people have many friends, but when he meets something, no one wants to help him. A friend is the first person to stand in front of you and help you when you are in trouble. Not those who accompany you to eat, drink and have fun every day, but those who have something to hide.
