      There are many TV programs on Chinese dishes, but few are like A Bite of China(舌尖上的中国) . The seven-part documentary (纪录片) tells us something interesting about what Chinese eat in different cultures and places.

      The different kinds of foods on TV are from sixty different places. You can see so much delicious food which can catch your eyes and stomachs. And you can also learn how to make the food. That's why the program becomes so popular.

      What's more, the program is not only about food. There are also many great stories between food and people. Liu Wen, a worker of CCTV-9, says the stories also show social changes.

      "As the program works as a window, the documentary wants to help people around the world know more about Chinese dishes and its cultures," he says.

      You can see the documentary on CCTV-1 or listen to it on CCTV-9 if you like it.
