A Bite of China: Celebrating the Chinese New Year/舌尖上的新年
This might be the best documentary to record the various Chinese cuisines all over China. Different foods become very shining with the skillful filming on the screen even you know they might be some normal food. And the director connected the food and the Spring Festival, the most important vocation for Chinese, well, and succeeded in making the movie a sentimental homesick one rather than a simple food documentary.
Best advice: do Never watch this documentary when you are hungry!
