To many students, joining social media (社交媒体) “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 (应用程序) such as Sina Weibo, WeChat (微信) and QQ.
“I love to check my friends’ updates (更新). 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 distances 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 (定位) function in any app, do not give your name, and do not post the photos of your residential area (小区),” said the police.

Dear Mr. Price,
I have eaten in your restaurant many times and have always been happy with the food and service. This makes what happened last Saturday even more disappointing(失望).
It was my son’s birthday so we booked a non-smoking table at your restaurant for 7:30 p.m. We arrived on time but were told that our table was not yet ready. At 8:00 p.m., we were given a table in the smoking area. I asked to move but I was told that there were no other tables. A lot of people were smoking so it was uncomfortable and unhealthy.
Our first waitress, Janet, was very polite and helpful. She gave us free drinks for waiting so long. Our food also came quickly and looked fresh and tasty. When my wife had eaten most of her meal, she found a dead cockroach(蟑螂)in her vegetables. She was shocked and wanted to leave. At first, the waitress told us it was a piece of garlic(作料).When we told her it had legs, she apologized
(="said" sorry) and took the food away.
We asked for the pay for my wife’ s meal bill, expecting not to pay for my wife’s meal. Nobody came. After 15 minutes, I asked to see the manager. The headwaiter told us that you were on holiday. I complained again about the horrible cockroach. He told me Janet had finished work. He didn’t believe my story and gave me a bill for three meals. I argued with him but was forced(被迫)to pay.
The waitress, Janet, was always friendly, but I would like an apology from your impolite headwaiter and a full refund(退款)for our meal. It cost $68. Until then, I will not be eating at your restaurant or recommending it to anyone.
You can contact me at 742-3254 or through e-mail if you want more information.
Thank you for your attention.
Yours sincerely,
Raymond Yuen
