The *Yulong Jing* (Jade Dragon Classic) is an acupuncture and moxibustion text transmitted by Master Wang from Wuyuan. The attribution to Bian Que is a pseudonym used to revere his Dao and sanctify the book. It is named "Jade Dragon" because jade is the essence of heaven and earth, and the dragon's divine transformations are extremely spiritual; the miraculous efficacy of this book is likewise. Since my youth, having received instruction from my relatives, I have traveled and practiced arts among Seven Min (Fujian) and Two Zhe (Zhejiang) for forty years. Whenever I encountered disease, I treated it, and treatment always yielded results. I believe in the Dao of this book: just as the luster of jade radiates outward, its brilliance grows more enduring over time; just as the dragon travels through the sky, bestowing boundless grace, its changes become ever more divine, yet remain unfathomable to people. Therefore, I bow and record the principles herein, noting the applications at the end of this volume.
