The three-day festival takes place from the 12nd to the 14th days of the fourth lunar month and conveys people’s wishes for good weather and a bountiful harvest.

The game is played on a yard filled with liquid mud. Two holes, measuring 80cm deep and 50cm wide, are dug at both ends of the yard, for the goals.

During the game, 16 local men are divided into two teams who try to score by pushing the ball into the goal of their opponents.

The ball used in the game is made of ironwood, measuring 20kg in weight and 40 cm in diameter. It is kept in the communal house and has been passed down from generation to generation.

People believe that each push of the ball into the pit symbolises the harmony of the earth and heaven, good weather, and a bumper harvest.

According to the elderly people in Van Village, the mud ball wrestling festival is a time-honoured practice which used to be organised annually, but it was interrupted by war for a long time.

After the national unification, this game was resumed but took place irregularly. Since 2002, according to village regulations, Van villagers will hold the festival in every four years.
