It is said that Cai Yin brought the two high monks, Shemoteng and Zhufalan, back to Luoyang. Liu Zhuang also wanted to know whether Buddhism was more profound or Taoist arts were more mysterious, so he scheduled a showdown between the masters of the Buddhist sect and the True Persons of the Daoist sect in the imperial court the next day.
The night passed without incident.
The morning court began, and the ministers loudly chanted long lives. Liu Zhuang asked the ministers to rise, and then Cai Yin invited the two high monks. The two monks joined their palms and walked step by step to the front of the court, bowing to Liu Zhuang from afar.
Liu Zhuang said, "Yesterday, my subjects were arguing, some saying Buddhist law is profound, others claiming Taoist arts are mysterious. I too am very interested in this. Now that the two high monks of the Buddhist sect have arrived, have my subjects summoned the True Men of Virtue from the Daoist sect?"
