Youth is like this. Some people are full of hope at the age of 18 and are invincible. They express their hope in the sunshine openly, while some people are unable to get out of the mud at the age of 18. The sun is very dazzling but always cannot shine into the dark corners. The teacher's indulgence and the indifference of bystanders push the young man into the abyss.
Purpose: I hope there will be less violence and more understanding
