During the Song Xuanhe era (1119-25), Huizong (r.1100-1126) provided meals for a thousand Daoists, only omitting a single name; when a Daoist suffering from leprosy requested a meal, the supervisor of the gate categorically refused this. At that time, Huizong was in conversation with the priest Lin Lingsu (1076-1120), when the Daoist suddenly appeared to his majesty, and he urgently sent people to deliver the meal. The Daoist scratched one of the hall pillars with something tucked in the sleeve of his robe and departed. Huizong saw and marveled at this, and rose to look, finding chalked writing that read:
Loud talk and empty words as if all alone,
Pity the wise monarch who cannot encounter truth.
If His Majesty asks his servant what is yet to come,
Pray attend to the springs of wu, wei, bing and ding.
It indeed turned out that in the bingwu and dingwei years of the Jingkang era (1126 and 1127), the two emperors suffered their northern troubles.

 This presumably refers to Huizong’s abdication in 1126 and the capture of Huizong and his son Qinzong by Jin forces in 1127.
