To many students, joining social media "circles" is now more important than making new friends in real life. And it's easy. If you have a cell phone, you can download apps such as Sina Weibo, WeChat and QQ. "I love to check my friends' updates . I also enjoy news and humor shared on social media," Said Ou Wei, 14, from Hongling Middle School in Shenzhen. Because of enjoying these, Ou _ himself from real life. "I love playing the plane-shooting game on WeChat, but have no interest in playing flying chess with my classmates," said Ou. Deng Yunyun, 14, from Jianfeng Middle School in Shanghai, said that social media had influenced their life. Recently his school held a basketball match, and a student hurt his leg. Instead of giving him some help, students were busy with updating micro blogs about the accident. "I think they need to learn to balance their real and online lives," said Deng, What makes parents and teachers worried is safety. "Many students are happy to tell their interests and personal information to their social media "friends". Such information could bring them danger," said Han Songjun, a teacher at Hongling Middle School. For example, WeChat's shake-shake function allows users to connect to other users close by. But the police warn about the danger of socializing in this way. "Be careful. Do not use the locating function in any app, do not give your name, and do not post the photos of your residential area ," said the police.
