Every spring in northern Phu Tho Province, locals celebrate Phet Hien Quan, a unique traditional festival that is held on the 13th day of the Lunar New Year.

Unlike other Tet traditions which revolve around introspective visits to the pagoda or jovial, nhậu-filled meals, Phet Hien Quan is characterized by a free-for-all among thousands of young men competing for "lucky balls", reports Tuoi Tre.

The event is meant to commemorate Thieu Hoa, a female Vietnamese general who helped the Trung sisters defeat Chinese invaders in 40 AD and is highlighted by an event wherein nine bamboo balls of various sizes are painted red and buried underground in a large field.

Said to give luck to the final holder, young men from neighboring villages are divided into teams of 10-20, each of which then battles for the lucky balls amidst physical violence and verbal assaults.
