Pingqiu Beidong Aomai (marriage and love) customs are mainly spread in Pingqiu Town, including Yandong, Sanjiang, Datong, Qimeng and other towns in Jinping County, and surrounding areas such as Tianzhu County, Jianhe County, Sansui County, and Zhenyuan County. Pingqiu Town is located in the northwest of Jinping County, 22 kilometers away from the county seat. It is the intersection of Jinping, Jianhe and Tianzhu counties. The terrain is an extension of the Leigong Mountains, with streams and canyons crisscrossing. It is known as "the customs of the northern Dong can be seen in Jiuzhaigou, and the customs of Jiuzhaigou can be seen in Pingqiu". Because the Dong people do not have their own writing, there is no evidence to prove the origin and historical development of the Pingqiu Beidong wedding customs. According to some local inscriptions and old people's oral traditions, it was popular as early as the Ming and Qing Dynasties. From the founding of the People's Republic of China to the "Cultural Revolution" period, its scale gradually shrank due to economic difficulties. Northern Dong wedding customs reflect the whole process of young men and women from knowing each other to falling in love and getting married, including the first meeting, building bridges, becoming a couple, matchmaking, proposing marriage, asking for horoscopes, carrying baskets, and setting betrothal gifts. Each link is based on songs, with songs as the medium and songs to convey feelings. For example, the first meeting: Man: We just came here, we just came to the waterside to sail the boat. We don’t know how deep the water is, we rowed together. Woman: We just came here, we just came to the garden platform. We just came under the flower trees, I hope the sky will build a bridge. Another example is the song of becoming a couple: Man: We are connected, we are so lucky to be together inside the garden gate. Thirty years have passed, and we will be together for sixty years. Woman: Listen carefully, you are interested and I am interested. You tell your parents at home to choose an auspicious day to get engaged. Through playing in the mountains and talking about love, young men and women find their "confidants" and then go home to report to their parents. The man asks a matchmaker to take gifts to the woman's family to ask for marriage. After obtaining the woman's consent, the engagement is arranged and an auspicious date is chosen for the wedding and banquet. Dong weddings are grand and warm. Both parties choose an auspicious date. On that day, the man invites more than ten or twenty young men to carry meat and set off firecrackers to the woman's house to pick up the bride. The woman sets up a door-blocking wine and requires the man to sing a song to open the door before entering. The man also sets up a banquet to welcome the bride, and invites singers, relatives and friends to drink and sing all night long. Among them are flower songs, wine songs, and big songs. Young men and women in the northern Dong play in the mountains in the "garden", use songs as a medium, use songs to express their feelings, and choose their own lovers. The whole process is carried out with songs, and the lyrics and tunes vary depending on the links. In addition, even if they are in free love, they still pay attention to "marrying in a formal way". The man needs to choose a matchmaker to negotiate and smooth things over at the homes of the man and woman before they can finally hold a banquet and get married. As an important part of the Northern Dong folk customs, the marriage customs of the Northern Dong in Pingqiu pursue and realize gender equality and freedom of marriage, reflecting its unique marriage ethics and values. In addition, the Northern Dong songs have a variety of tunes, which are melodious and rich in content, and have important research and appreciation value. The marriage customs of the Northern Dong in Pingqiu are not passed down by master and apprentice, but are passed down orally from generation to generation. However, as the singers are getting older, the vernacular and Dong songs circulated among the people have become difficult to pass on. In addition, a large number of young people go out to work, and the material and spiritual and cultural life are constantly sinicized, which makes the living habits of the Dong people gradually disappear, and their marriage customs have also begun to fade out of the vision of young people, facing a survival crisis.
