The triannual festival is held on the 4th day of the fourth lunar month (leap year).
In 2018, the Phai Lua festival was recognised as a national intangible cultural heritage. This is a traditional and unique festival associated with the river legend of the people of Hong Phong Commune and neighbouring communes, where the Bac Giang River flows.
Coming to the festival, visitors will be immersed in folk games such as boat racing, swimming competitions, sli singing, etc.
The festival features a wide range of activities including displaying and introducing cultural beauty, local agricultural and forestry products; cultural exchange between villages, agencies, units, and schools; a contest to learn about the geological heritage and the Phai Lua festival for 19 teams, from 19 communes and towns.
After three years of the COVID-19 epidemic, the Phai Lua festival has officially reopened, attracting thousands of tourists and local people to participate.
