March 3rd Festival is a traditional festival for the Li people in Hainan to mourn their hardworking and brave ancestors and express their yearning for love and happiness. There are two versions of the origin of March 3rd Festival. The first version says that it is said that a long time ago, the Li people living on the banks of the Changhua River suffered a severe flood, killing people and livestock, leaving only a pair of siblings named Tianfei and Nanyin. After the two siblings grew up, they decided to find their partners separately and agreed to meet at the foot of Yanwoling every March 3rd. From then on, Nanyin and Tianfei Niangzi and their descendants would return here to welcome spring every March 3rd. In order to commemorate them, the Li family called the stone cave Niangmu Cave, and March 3rd naturally became a grand festival for the Li family. The second version says that it is said that a long time ago, there was a crow spirit in the stone cave that did many evil things, making it impossible for the people to live and work in peace. One day, the crow spirit captured the beautiful Li girl O'Niang. On March 3rd of that year, O'Niang's lover Agui took a sharp knife and bow and arrow to the mountain to save O'Niang, but was killed by the crow spirit. O'Niang was extremely sad when she heard the news. She finally killed the crow spirit while it was sleeping, avenging Agui and eliminating a great harm for the Li people. O'Niang never married. Every year on the third day of the third lunar month, she would go to O'Xian Cave to sing the love songs she and Agui had when they were in love. Later, in order to commemorate her, the Li people named this cave O'Niang Cave (Changjiang). Every year on the third day of the third lunar month, unmarried young Li men and women nearby would go to O'Xian Ridge1, singing love songs to find their loved ones. This activity has expanded year by year and spread to various Li people's residential areas in Hainan, forming a grand traditional festival among the Li people in Hainan. There are records related to "March 3" in the historical books of the Song Dynasty. Fan Chengda of the Song Dynasty wrote in Guihai Yuhengzhi: "In spring, there is a swing party. Men and women from neighboring villages dress up and come to play, hand in hand, singing and answering each other, which is called a play." Since ancient times, on the third day of the third lunar month every year, the Li people would wear festive costumes, carry mountain baskets of rice wine, bring bamboo tubes of fragrant rice, and gather from all directions to worship their ancestors, or meet in groups of three or five, sing, dance, and play percussion instruments to celebrate the festival. Young men and women even take advantage of the festival to revel, make friends with songs, express their feelings with dances, and indulge in the river of love with happiness. They will not say goodbye until dawn, and make an appointment to meet again on the third day of the third lunar month next year. The Li people's March 3rd Festival has a very broad mass base. With the changes of the times, the content of the celebration has become increasingly diverse, but singing, folk sports competitions, ethnic songs and dances, and wedding performances are still the most basic content. The March 3rd Festival is a cultural resource passed down by the Li people for thousands of years, and it is the most specific and typical expression of the Li culture. In 1984, based on the wishes and demands of the Li people, the Guangdong Provincial People's Congress and the Guangdong Provincial People's Government decided to designate March 3rd as a traditional festival of the Li people.
