Comment by contingencies

Things Chinese consume all the time that they typically don't know came from somewhere else: baozi (came with the Mongols from Ottoman cuisine), chicken (first domesticated in the Brahmaputra/Bengal/Myanmar region), chilli, corn, peanuts, tea (SEA border of Yunnan, very un-Chinese until recently), tomato. The source(s) of initial rice domestication are still unclear, but much of China (north and central China) did not eat rice as a daily staple for a significant part of Chinese history.
