"When people gather firewood, the flame is high", "When people are United, Mount Tai is the top, and people are United". These famous sayings from ancient times to the present are the truth of unity and cooperation.

A woman from a certain country came to a primary school in China and asked five children to cooperate to do one thing. The lady took out a bottle with five balls in it. She asked all five balls to pass in seven seconds, otherwise she would be drowned by the water in the bottle. Only one ball can pass through the bottle mouth at a time, and the last ball is in danger of drowning. The five children thought about it, then whispered a few words to each other, indicating that the game could begin. I saw that the youngest child pulled the ball out first, the second, third and fourth balls came out in turn, and the oldest child came out last. In 7 seconds, all five balls were pulled out. The lady was shocked by the five China children and shed tears of excitement, because she knew that she had done this experiment many times in other countries, and all the children were struggling to pull it out, but no one could come out of the bottle.

The five children in China in this story, it is because of their unity and cooperation that they have successfully passed through the difficulties. In real life, when we encounter difficulties, we can find teachers and classmates and discuss solutions with them. In this way, no matter how big the difficulty is, it will become insignificant.
