Let Whay (Lethwei) is an unarmed Burmese martial art. It is similar to related styles of Indochinese kickboxing, namely Muay Thai from Thailand, Pradal Serey from Cambodia, Muay
Lao from Laos and Tomoi from Malaysia.
In ancient times, matches were held for entertainment and were popular with every strata of society. Participation was opened to any male, whether king or commoner. At that time, matches
took place in sandpits instead of rings. Boxers fought without protective equipment, only wrapping their hands in hemp or gauze. There were no draws and no point system—the fight went on
until one of the participants was knocked out or could no longer continue.
