It is common for a person to feel lonely when he has just entered the university and is a stranger. This is mainly because I didn't take the initiative to interact with my classmates and exchange ideas. Understanding and interacting with classmates can eliminate the troubles caused by loneliness. If you know each other, ask them where their home is, how they came from, and so on. If you ask him to be caring and attentive, he will be sincere, probably a fellow villager. Putting down the ideological burden and talking and laughing with classmates can change their lonely psychology.
