 When Zhong Hui received news about their defection, he suggested to Sima Zhao to ask Quan Hui and Quan Yí to write a secret letter to Quan Yì and lie to him that Sun Chen was displeased by Quan Yì's failure to conquer Shouchun and wanted to execute Quan Yì's family, hence they decided to defect to Wei.Quan Yì became fearful so he brought along his troops and surrendered to Sima Zhao.Without support from Wu, Zhuge Dan's rebels were defeated by Sima Zhao's forces and Shouchun was taken back by Wei.
