what do Chinese people eat the most?
It is interesting. Because of your search I tried to find a comparison of rice consumption per capita by country and the 1st thing Google had given was this website in Japanese:
According to this website, the average consumption in China is 107.2kg per person per year, not even in the world top 5. The champion goes to Cambodia at 237.5kg, and a close runner-up is Vietnam, at 236.5kg. It is a bit surprising though to know the average consumption in Japan is merely 55.2kg.
