As most university students are packing their bags,boarding trains or flying home for the Spring Festival,some will stay behind to spend the holiday on campus.

Zhou Yunyun,22,a senior finance major at Jilin University,has decided that instead of traveling to Hainan province,he will kill the time by playing computer games with his online friends.

“I'm used to chatting and playing with them every day.It’s just fun to make friends this way,”he said.“When I returned home in past years,my relatives always asked me a lot of questions about my plans after graduation.They had high expectations of me,which made me feel stressed,” said Zhou.

The campus,usually lively,will probably turn into a death town,with most restaurants,shops and student centers closed during the break.But there are also a few advantages,according to Jia Debao,2 1,a junior majoring in administration at China Agricultural University.“I might feel a bit lonely,but at least I can stay away from my parents’ complaining and enjoy the peaceful and quiet stay,” he said.“More importantly,I can enjoy the high speed of the Internet,I can always find empty seats in classrooms,and I don’t have to wait to use the bathroorm” But education experts recommend students who stay on campus to come up with more interactive plans.That’s because communication on the Internet can’t replace real life interpersonal relationships.

Society has promoted a kind of“couch potato" or close-in culture among some young people, according to Shi Tongyu, a researcher at the Chinese Academy of Social Sciences. He warned that this kind of lifestyle can damage students’ mental and physical development.

“When you constantly stare at a computer screen and type on your keyboard,you gradually lose the ability to socialize and survive normally,"said Shi.“A human’s most important task is to survive,which cannot be completed by staying at home all the time. Instead,it must be achieved through real life experience and communication.”
