Having a big reputation and high visibility doesn't mean one is a "renowned teacher." Fame and fortune often burden one with superficial acclaim. A true "renowned teacher" is an "enlightened teacher," not only possessing exceptional skills but also demonstrating exemplary ethics. They are adept at tailoring their teaching to suit each student, taking their responsibilities seriously and demanding discipline. Genuine renowned teachers don't indulge in obscure and mystical martial arts theories; instead, they can elucidate martial arts theories in a clear and practical manner. They guide their students to integrate knowledge and action, truly embodying the martial arts.
