Two fields (pitches) are separated in the middle by a lane with the width of 2 meters on the ground ("Chinese wall"). The guard walks on the lane. The players run between the pitches so as not to be caught by the guard. If they are captured, then they have to stand on the lane of "Chinese wall" and help the guard to catch the others.
