"Yongxing" in Yanbian County was formerly known as "Lasatian". It was established as a market town during the Jiajing period of the Ming Dynasty and was an important post station on the ancient Tea-Horse Road. The Gelao people living in Xinmin Village (formerly known as "Ba'e" and "Baai") in the town call themselves Yelao. The Gelao people believe that the village is inhabited by people and gods. People cannot live without gods, and gods cannot live without people. Sacred trees, sacred mountains, and gods are part of their lives. "Sending New Year's Festival" is a traditional festival that Yelao has inherited to this day to worship gods and ancestors, worship nature, celebrate the harvest, bid farewell to the old and welcome the new, bless peace, and unite the tribesmen. It is the most important festival for the Gelao people. On the sixth day of the first lunar month every year, Bimu (called Dongba or monk in Chinese) assigns young men to go up the mountain to collect seven different kinds of wild flower branches, put on a palm plate, carry a backpack and go to the village from house to house to collect money and goods donated voluntarily by the tribesmen to buy firecrackers and sacrificial supplies. Early in the morning of the seventh day, Bimu led all the tribesmen to the forest behind the village, bringing the pre-brewed "Zhagan wine" as well as meat and offerings to a thousand-year-old tree with green cypress, yellow loblolly and night wormwood. They hung sheep heads and red ribbons on the tree, set up a big pot to cook "hundreds of meat", used seven-color flower branches to build a sacrificial altar, and offered sacrifices with "Zhagan wine", pork and offerings, begging the gods to bless the tribesmen with good health, good weather, prosperous livestock and good harvests in the coming year. Women over the age of 12 are not allowed to enter the sacrificial site. In June 2011, the "Gelao New Year's Festival" was announced by the Sichuan Provincial Government as the third batch of Sichuan Province's intangible cultural heritage list.
