Tangtuan (called "tangtuan" in Chinese) is made of glutinous rice flour wrapping, leaf fat, sugar and black sesame. The skin is thin, smooth, white and shiny. Not all visitors to Ningbo have the luck in enjoying the Top Ten Ningbo Dishes. However, one thing that any visitor can not miss is the Ningbo stuffed lard and sesame dumpling, just like one who goes to Beijing must go to the Great Wall. In Ningbo, as in all China, sweet dumpling is a symbol of family reunion and happiness and in Ningbo it is a local custom for all family members to have dumplings on the morning of the first day of the lunar year. Dumplings are very popular in the city; however, to enjoy the most delicious, one has to go to Gang Ya Gou Sweet food Buffet, as saying goes: "Home-made dumplings are common things, but nothing is better than the dumplings in Gang Ya Gou."
