And it's not just exam papers. Popular TV dramas and stars have also become public examples for safety education. The recent Chinese TV hit Ode to Joy, a TV drama telling life stories of five girls in Shanghai, is one of them. In the first episode, the five leading characters are trapped in an elevator and one of them presses each floor button in order to stop the elevator from falling, which earned a slew of likes on social media and was cited as a good example for self aid.

Meanwhile, negative examples for public teaching are also commonly seen. In the same drama, one protagonist parks her car in the middle of a road in a rage before her boyfriend drives it away, which drew critics from Hunan Provincial Public Security. The security officers pointed it out as a wrong-doing in their official Weibo, Twitter-like social media, account and stressed that the behavior shown in the TV plot will cause traffic congestion or even fatal accident, calling the public not to follow the example.

Another incident that has been cited is of actor Wang Kai taking a selfie on Weibo with him sitting inside a car, with the caption reading "Love you life and do not use your phone when driving." The post was immediately retweeted by local security forces reminding him and the public to wear the seatbelt; Hong Kong actor and singer Aaron Kwok was also tagged by the security officers as a wrong example on social media when he posted a picture showing him holding his girlfriend's hand and driving with the other hand.

The increasing number of such examples and discussions reflect the rise of social power and influence of entertainment celebrities, which is hard to take it simply as good or bad. But one thing is for sure - more power requires more responsibility. Maybe it's time for the stars to think how to set up a good example for their fans, not only in their work, but also in real life, isn't it?
