On the occasion of Chen Sui, the wise master, the founder of Tiantai Sect, dreamed that he was a saint and admired the master as a true Buddha when he traveled in Yuquan Mountain, Jingzhou. He explained that Fahua is a true religion, hoping that the master would overcome his Samadhi and be accepted by the master, so Guan Gong converted to the wise master and instructed him to build a temple. Later, the master really got a treasure trove of geomantic omen here, and the spiritual spring gushed out without digging, so yuquan temple was established. This temple became the ancestral home of Tiantai Sect outside Tiantai Mountain and made Guan Gong a protector. Since then, Guan Gong has officially changed from a folk righteous god to a Buddhist protector, which has been passed down to this day.
