Bac Son market, where there is a beautiful stilt house village.

The weekly market in Bắc Sơn commune is a distinctive cultural feature of the Northwest region, where people of the Tày, Nùng, Dao, and other ethnic groups gather to trade agricultural products, handicrafts, and exchange traditional goods from the Lạng Sơn mountainous area. Nearby, Quỳnh Sơn village is famous for its hundreds of traditional stilt houses with tiled roofs in the yin-yang style, creating a peaceful and picturesque rural landscape, especially when situated between the Bắc Sơn valley and the vibrant rice fields. This village is also part of the Lạng Sơn Geopark (UNESCO Geopark), where visitors can explore geological values alongside local culture, traditional yin-yang tile-making craft villages, and local customs.
