It is impossible to think about “growing up” in modern America without considering “youth culture” which every young person—even those who do not attend public schools—is confronted by and must deal with. It is impossible to be so isolated that we are untouched by the surrounding culture. Nor should we wish to be—as we are called to be—salt and light in a very confused and broken world. Popular culture deserves neither uncritical acceptance nor knee-jerk rejection, but thoughtful critique（批评）.

On the contrary, China paid too little attention to youth culture in the past. However, with society developing, more and more people have realized the importance of analyzing, understanding and promoting youth culture.

About 100,000 young Chinese people from all over the world will attend the first China Youth Culture Week scheduled to open Saturday in Shenzhen’s China Folk Culture Villages, a press conference was told Thursday.

A series of cultural activities will be staged from Saturday to Wednesday, including a huge performance expected to challenge for a listing in the Guinness Book of World Records.

About 10,000 young people will attend the opening ceremony Saturday. A final list of the Chinese Youth Idol Award to five outstanding young Chinese was announced at the conference. They are the country’s first astronaut, Yang Liwei, Chinese NBA star, Yao Ming, IT entrepreneur, Ding Lei, anchorperson, Wu Xiaoli, and Olympic Games gold medalist, Deng Yaping. The youth idols were selected by

Chinese teenagers with 380,000 votes cast nationwide.

During the past two months, the organizers received more than 3,000 applications from young people in Hong Kong and Macao who wanted to take part in the performance.
