Youth, friendship and love are the main themes of this year’s Chinese movies, such as So Young(《致青春》) and American Dreams in China(《中国合伙人》). Tiny Times(《小时代》), one of the most popular movies this summer, also has the same features.

The movie was based on author and director Guo Jingming’s novel of the same name. It tells a story about four girls who come from different backgrounds and of different personalities. Since it was shown on June 27, Tiny Times has made 483 million yuan at the box office. The sequel(续集) of it was shown on Aug 8 and it has also been a big box office hit.

Cao Yuhan, 13, a high school student at Beijing Jianhua Experimental School, is a big fan of the movie. “I’m deeply touched by their friendship,” Cao said. “When Nan Xiwang is in trouble, the other three girls try their best to help her, even running barefoot in the snow. However, not everyone has had good things to say. The people’s Daily said that the film went too far in encouraging youths to become materialistic(物质至上主义的). Film commentator Raymond Zhou wrote on his online blog that “Buying luxury goods seems as a way to express love or friendship, and the word ‘money’ is repeated over and over again. Song Kexin, 14, a high school student at Zhida Middle School in Taiyuan, Shanxi, shows a typical example of a fan’s attitude(态度). And that’s to look for the positive value. “That movie is a little far from our daily life. My friends and I are not having parties every day,” Song said, “But I admire Tang Wanru’s optimistic attitude. She’s always looking at the bright side of life. I should learn from her.”
