Among more than 260 traditional festivals in Lang Son Province, Pac Mong festival is considered one of the greatest ones, attracting thousands of people from all over the country. This is also an event that triggers the beginning of the festival season in the province every spring.
Pac Mong Festival is organized in the 5th day of a lunar year in Quang Lac village, Lang Son province. It is closely related to the Long Tong (come down to the field) Festival, a celebration of the Tay and Nung ethnic group to start a new harvest.
Even though the festival does not start until the 5th day, since the afternoon of the 4th day of the year, many people from other regions have gathered in the village. Most of them are the young men and girls from Dong Mo (Chi Lang District) and Dong Dang (Cao Loc District). When the night falls, after the worshiping process inside the King Dinh Tien Hoang Temple in the center of the village, people start celebrating. The young men and girls participate in the various activities such as Lion/ Dragon Dance, Sli Singing Contest, Luon Singing Contest, etc. On the fields full of Mua and Sim flowers, couples sit together and sing cheerfully. Their voices and laughter mesmerize the tourists from other regions.
On the next morning, the inhabitants in Cao Kiet, Xien Cu, Ban Quach, Khuon Nha, Pac Cap, Nghuon Nghien village have prepared their gifts to the God. These gifts, usually in the form of food and fruits, are placed on the side of the paddy fields so that people can worship and then eat the food there.
Despite the fact that festival is celebrated by the local inhabitant in Lang Son, the Tay and Nung ethnic people from other districts of the province also love to come and enjoy this event because they believe attending the festival would bring them a lucky year.
