This is a practical routine in Shaolinquan. Movements such as plant, hammer and strike should be conducted forcefully and quickly as if he was fighting a tiger in a forest. While performing, you should move like the wind, stand like a nail with your eyes as bright as lightning, or flash your punches on the enemy. All of the movements are conducted almost in one breath.This product is manufactured on demand using DVD-R recordable media. Amazon.com's standard return policy will apply.
