In the fourth year, an edict was issued: 'The scriptural teachings of Persia originated from Daqin. The Persian monasteries in the two capitals should be renamed Daqin.' / The Daoist priest Wu Yun of Mount Zhongyue was summoned for an audience. When asked about the essentials of the Dao, he replied, 'Among those deep in the Dao, none surpass the five thousand words of Laozi.' When asked further about methods of cultivating transcendence and immortality, he replied, 'These are matters for rustic men who pursue them through accumulated years; they are not things upon which a ruler of men should bestow his mind.' At that time, the eunuch Gao Lishi, who had long served the Buddha, slandered him before the Emperor; Wu Yun then took his leave to return to Mount Mao. Having been dismissed, Yun composed a treatise to disparage the Buddhist teachings. Chen Shaoyou, Surveillance Commissioner of Western Zhe, invited Dharma Master Shenyong to settle the dispute. Yong agreed to a face-to-face debate on heterodoxy and orthodoxy. No sooner had the banners and drums faced each other than Yun suffered utter defeat. Yong then composed the Fanniexie Lun (Treatise on Overturning Heterodoxy) to attack the remaining partisans. Shaoyou reported this to the court, and an order was issued appointing Yong as the Buddhist Controller (Yong was the successor to Zuoxi).
