Some martial arts, particularly the traditional Chinese martial arts, also teach side disciplines such as bone-setting, qigong, acupuncture, acupressure (tui na), and other aspects of traditional Chinese medicine
Ninjutsu (??, Ninjutsu?) started out as a set of survival skills that were used by groups of people who lived in mountainous regions of Japan. They were self-reliant, and had a strong affinity with nature.
These techniques used to hunt and fight eventually developed and became the strategic base of the Ninjutsu martial art. The ninja clans used their art to ensure their survival in a time of violent political turmoil. It also included methods of gathering information, non-detection, avoidance, and misdirection techniques. Ninjutsu can also involve training in disguise, escape, concealment, archery, medicine, and explosives.
