It was

20 by 20 meters square and there was a reception area set up nearby. The fight
was not to be scored, but to continue until a decisive winner emerged. Before the
fight, Muen Han was oiled with herbal ointment, and he wore amulets on his upper
arms. He was then carried to the ring on the shoulders of a friend.
When the fight began, it was clear that the foreigner was much heavier, taller,
and stronger than Muen Han.
