The jiazi 饺子 is a common Chinese dumpling which generally consists of minced meat and finely chopped vegetables wrapped into a thin and elastic piece of dough skin. Popular meat fillings include ground pork, ground beef, ground chicken, shrimp, and even fish. Popular mixtures include pork with Chinese cabbage, pork with garlic chives, pork and shrimp with veggies, pork with spring onion, and garlic chives with scrambled eggs. Filling mixtures vary depending on personal tastes and region. Jiaozi are usually boiled or steamed. Jiaozi is a traditional dish eaten on Chinese New Year's Eve, the 5th day of Chinese New Year, and special family reunions. Extended family members gather together to make dumplings. It is also eaten for farewell to family members or friends. In North China, dumplings are eaten with a dipping sauce made of vinegar and chili oil or paste, and occasionally with some soy sauce added in.
