Martial art has always taken different sources of inspiration, different styles of close combat, has been inspired by animals, such as the monkey, the crane, mantis, snake, tiger. Applying techniques to defeat the opponent effectively. All these styles are an art that takes time for decades, it can even take a lifetime to perfect those fighting styles.
