Crane VS Snake
One common story is told of Zhang Sanfeng, a Taoist monk of the 12th century, who learned Tao Yin breathing exercises from his Taoist teachers, as well as martial arts from the Buddhist Shaolin monastery. One day on Wudang mountain, he witnessed a fight between a snake and a crane. The crane attacked, stabbing at the snake, but the snake managed to evade. The snake fought back with whip-like attacks of its own, but the crane deflected these attacks by fiercely spreading its wings. Inspired by this scene, it is said that Zhang Sanfeng developed Tai Chi, which mimicked the fluid movements of the snake and crane he had witnessed.
