The Tian Guangzong 田光宗

Tian Guangzong, a figure of the Ming Dynasty (1368–1644), became a Taoist monk at Wudang Mountain and styled himself "Zizhai" (the "Self-Disciplined Hermit"). He was known for his ascetic lifestyle and strict adherence to moral conduct: every midnight, he would go to the main gate (of the Taoist temple) to pay homage to the Big Dipper (a constellation revered in Taoism as a symbol of divine authority and longevity). He did not consume food cooked with fire (a practice in certain Taoist ascetic traditions, emphasizing purification by avoiding "worldly" food prepared with fire).

Later, he met Zhang Feng (a Taoist practitioner; the name may have alternative spellings or variants), who taught him extraordinary Taoist magical arts and techniques. During the Jiajing reign period (1522–1566) of the Ming Dynasty, when the imperial court issued an order to summon him (to serve the court or offer advice), he retreated into the back mountains (of Wudang Mountain) and his final whereabouts became unknown.
