Chinese people like to eat together, which is a tradition that can be traced back a long time ago. It reflects the Chinese notion of union versus division----round tables, round dishes, and round bowls all symbolize union and perfection. Dishes are usually placed at the center of the table so that everyone around the table can share them. A hot pot, in particular, adds to the atmosphere of harmony and union. A recent book by an American Sinologist holds that the Chinese collective tradition developed out of the practice of eating together.
