All the world's a stage for wacky teacher Mi Gao

Among my childhood friends, Mi Gao is exceptional. He is both a university lecturer and performance artist and has some ingenious methods to ensure his students - the "post-90s" generation famous for their independence and disobedience - get the point.

Mi recently spotted a TV ad promoting new items at a fast-food restaurant and turned the ad into a lesson that helped the kids discover the difference between real life and the fantasy one on movie screens.

He asked his students to dress up like youths bursting with hormones, like the ones you see in TV ads. Then he walked into a fast-food restaurant, bought the latest product being promoted and put on his favorite stage prop: a pair of sunglasses.
