When being chased by bandits, Yang Jinglan and Ji Yingying got separated.Ji Yingying fled to the cave entrance with Sheng Fengze and others. She believed that it was impossible for Sheng Fengze to take only Chi Hu. She asked Sang Shiro to do something to deliberately lure the bandits to see them.Sheng Fengze felt that Ji Yingying's plan would be miscalculated, and the bandits would not believe those traps.
Ji Yingying deliberately walked in front of the bandits. When the bandits ordered to fire arrows, she pulled Sheng Fengze and jumped into the trap.Yang Jinglan followed Zhenjing to find them and bluntly said that Sheng Fengze was not honest enough. According to a letter from Yizhou, he said that Tibetan businessmen colluded with Yizhou officials to disrupt Jinye and ordered Sheng Fengze to be detained.
