The prison held a nine-square grid competition at the activity center on August 28, with a total of 40 inmates participating.

    This game tests the inmates' pitching accuracy and on-the-spot stability. Everyone who enters the internment camp strives to aim at the nine-square grid and throws the ball. Those who hit more hits will be applauded by the inmates watching. Those who hit the few hits will also maintain a sportsman's spirit to complete the game. The team host won the championship.
