Chumok is the food similar to Jiaozi (the Chinese dumpling), which is the favorite food in China, especially northern China. Method of making: put some chopped meat on a piece of flat round dough strip and roll up it, put the ends together, just as how Chinese people make Jiaozi. Tu-pa is the food for the family reunion dinner, usually held on December 29 of the Tibetan lunar calendar. Sometimes small pieces of stones, capsicums, charcoals or wool threads are put in Tu-pa, each representing a special meaning. Stone means that the people who happen to pick up this Tu-pa will be stonehearted in the next year. Woolen thread means a kind heart. Charcoal means the vicious mind. Capsicum means a loose tongue. Of course those special Tu-pas do not really mean those bad things. They are just for fun. No matter who happen to take that Tu-pa, they immediately spit it out. People laugh happily then. This habit really adds to the fun and happiness of the festival.
