List of The 72 Shaolin Martial Arts - A Series of Blows

A Series of Blows (排打功, Pái dǎ gōng) is similar to Iron shirt except that it is purely external and contains none of the internal elements of the latter. During training, a practitioner hits his body with a block of wood, then a brick, and subsequently a block of iron as he progresses. His body will become invulnerable to bare-hand strikes after mastering the skills but the practitioner is not protected from weapon-based attacks.
