Jeet Kune Do was not a mature martial art. Its creator passed away suddenly before he could perfect it.
Earlier on, Bruce Lee had felt that Jeet Kune Do was not mature, which was why he forbade disciples from opening schools and teaching under the name "Jeet Kune Do." This command was not lifted before his sudden death. After his death, many of his sect members and disciples attempted to simplify and create based on what Jeet Kune Do already had, while others tried to establish rules to promote commercialization.
Some simply left the circle, adhering to Bruce Lee's command, only incorporating the philosophy of Jeet Kune Do into other martial arts they practiced, and opened martial arts schools without using the name Jeet Kune Do.
When Lu Xuanyu arrived in Seattle, that martial arts school was already quite rundown.
"Can a community or sect really form spontaneously?" Lu Xuanyu asked. "Can it be successful without a leader?"
