In a sunny temple courtyard in Vietnam, Le Van Thang pushes an iron rod hard against his eye socket and tries to make it bend -- his dizzying strength honed through years of practising centuries-old martial art Thien Mon Dao.

Thang, 28, is one of an increasing number of Vietnamese to find refuge in a sport that grew out of a need to protect the country from invaders, but now offers a route to mental wellbeing in the rapidly changing Communist nation.
