The Phong Luu Khau Vai Market is a unique cultural event that takes place only once a year, on the 27th day of the third lunar month. The tradition began in 1919 as a way to celebrate human-to-human relationships and the love between couples. The market’s social customs and beliefs were recognised as a national intangible cultural heritage by the Ministry of Culture, Sports and Tourism in 2021.  Visitors can also take part in various traditional folk games at the festival, and enjoy a scenic boat ride along the Nho Que River at the foot of Ma Pi Leng Pass, one of the most stunning rivers in Vietnam./.
