The first frost Festival of Zhuang nationality is most distinctive in Xialei Town, daxin county, and its origin is related to the legend of Xialei Tusi and celebrating the harvest. According to legend, Xu Wenying, the 14th Tusi, and his wife Cen Yuyin, the daughter of Hu Run Tusi, once rode an ox with her husband to the coastal areas of Fujian and Vietnam in the late Qing Dynasty to fight against Japan. Because Cen Yuyin rode an ox to fight, he was called "Yamo". "Ya" is the name for old women in Zhuang language, and "Mo" means ox. Cen Yuyin's triumph against aggression coincided with the first frost Festival. In memory of Xu Wenying and Cen Yuyin, the people of Xialei built the Yuyin Temple (Temple Yamo), and on first frost Day, the people carried the portrait of Yuyin and held a wandering activity. There are two different legends about Cen Yuyin's deeds. One is that Cen Yuyin, a Zhuang woman, was superb in archery and brave. She once led troops to Guangdong and Fujian coastal areas to fight against the Japanese pirates. She used her troops decisively, and expected things to be like a god. She defeated the invading Japanese pirates many times and was rewarded by the emperor. Finally, she disarmed and returned to her hometown until her death. People held sacrifices to commemorate her defeat in first frost, which gradually became the first frost Festival. On the other hand, she and her husband, in order to defend the peace and property of the Zhuang people and lead troops to resist the invading enemy, won a great victory on the day of first frost, so the local people celebrated for three days and made it a festival. Every day before first frost, Zhuang people from all over the country spend the night in villages near Xialei, and the next morning they go to Yuyin Temple for worship. It is said that in the Qing Dynasty, local state officials also prepared offerings to attend sacrifices. After the sacrifice, the masses returned and performed lion dances, Zhuang operas, folk songs and other activities nearby to celebrate the festival of remembering national heroes. Festivals have a history of more than 300 years.
