The Chinese martial art of wushu can be practiced as either a full contact sport or as an exhibition, but there’s no doubt that the combatants bring an unparalleled level of intensity to both.

The pair took part in an exhibition known as duilian, which pits a bare-handed combatant against a weapon-wielding opponent. Credit: YouTube/Tony Lao
