Because they haven't found their goals yet, in their twenties, when they arrive at the university, you will find that there are many confused young people who choose a certain major, but they don't know what they can learn from this major, and they don't know whether to take the postgraduate entrance examination or find a job four years later, so they are very confused. I just sit in the dormitory all day playing games, playing mobile phones, brushing Weibo and watching TV dramas. I have no vitality at all.

They live like greasy middle-aged people, no, not even middle-aged people. At the very least, middle-aged people have their own pursuits and jobs, and they are very clear about their responsibilities. But these young people in their twenties don't know where the future is, they are confused all day and live untidy in the dormitory.

However, all this is temporary. They just don't know their goals for the time being. Many people will wake up in their sophomore and junior years and start making plans for their future lives.
