Mud wrestling with a ball was a traditional game organized every four year in Van village, Bac Ninh province, the north of Vietnam.
Like basket ball, but instead of the baskets hanging up, here there were two holes (like a goal) and the playing ground was filled up with wet mud, there were 16 players divided into two teams, they competed vigorously to score by putting the heavy wooden ball in their competitors's hole.
