answere to your question about JING
Wu Shu is the chinese word for martial art. Unfortunately, this term (wushu) in American is properly translated as demonstration martial art.
JING has highly qualified (sport) wushu instructors and students affiliated with the International Wushu Federation, but they do not teach true fighting. They do not advertise that they teach street fighting.
What they advertise is truthful:
they are a wushu school
they are authentic (they have afficliation and credentials as authentic IWF instructors and students)
they teach Chinese martial arts for sport purposes and health purposes.
they are not a mcdojo, since they are really not teaching a real martial art and street fighting!
By the way, Jet Li is a five time World Wushu champion, and has participated in many choreographed fight sets in competitions, but has never participated in a tournament fight.
