An ancient ninja art form founded by the Chang family. It originated from China but was more commonly practised in Korea until its illegalisation in 1749. The grand master in Korea , Pato Won Hee, only fully trained a few chosen disciples. These privellidged few went on to pass there knowledge onto others through martial arts schools and academies in countries outside of Korea. Currently Pin Juk-Seow (pjs) is not said to be safe enough to practice in public so is banned from most countries of the world.
