It's the end of class. When the bell rings, students of a Foreign Languages School in Shenzhen quickly take out their mobile phones. They like to log on (登录) to their micro blogs to check the funny things that have happened in the last hour.
Micro blogging has swept the country during the last few years. Recent surveys show that most students in middle schools have a micro blog, and some even update their blogs more than five times a day.
"We learn many fresh and interesting things on micro blogs and they have become popular topics in class," said Liang Jianmin, 14, a student from Harbin No. 3 Middle School. "If you do not know about them, you are out.”
It is also a great place for students to relax." My parents always ask me to study hard, and encourage me before exams, but actually it adds pressure," said Zhang Yazhe, 15, a student from a Foreign Languages School. "When I share these feelings on my micro blog, I get many replies from friends in the same situation, which makes me feel better."
But parents are worried that micro blogging could be a waste of time. Some misleading messages may even be dangerous to kids.
Shen Mingde, a professor, suggests parents not worry too much that kids are crazy about micro blogging. Instead， however, it can also become a window for parents to understand their children. "If parents can read their children's micro blogs, they'll know their thoughts, it can lead to better communication and solutions to problems," he said.
He also gives some advice to kids.
Don't micro blog for more than one hour a day.
Never micro blog in class.
Try to talk face to face with people from time to time.
Be critical(批判性的). Not all the messages on the micro blog are true.
