A Bite of China has become a hot topic of discussion on the Internet in China since it’s first shown on China Central Television (CCTV). This TV program is a documentary series about traditional Chinese food.

According to World Journal, it is a great attraction for more than one hundred million Chinese audience (观众). Most of them don’t see this program as an ordinary food show, because it shows them the value and quality of Chinese food, as well as the changes in society today. The audience are also given the chance to see how hard the cooks and farmers have to work to produce such wonderful Chinese food.

A Bite of China makes Chinese people think back to their cooking traditions, most of which have been forgotten in today’s busy life. Chen Xiaoqing, the lead director of the series, says that the program is not only about eating, but also about traditional habits and historical heritage(遗产) Chen’s friend, Liu Wen, says, “We also wanted to show international audience what modern China is like.”
