The Princes of Qinghe and Pingyuan had been arguing over a land dispute for the past eight years, with Sun Li, the governor of Ji Province, after consulting with Sima Yi, arguing that a map from the Palace Archives made during the time of the latter prince's enfeoffment should be used, which would favour Pingyuan's claim, but Cao Shuang preferred the plaint of the Prince of Qinghe, and so dismissed the appeal. Sun Li sent a memorial in a forceful tone, and Cao Shuang, in anger, banished him from his position for five years. However, he was eventually reinstated as the governor of Bing Province, and visited Sima Yi before taking his leave. Sima Yi saw that something was amiss, and he asked him if he thought it a small thing to be made the governor of Bing Province, or if he instead felt regret for having got himself involved in this whole affair. Sun Li, in tears, said that he didn't take official ranks or past affairs to heart, but that he was worried about the dynasty's future. Sima Yi replied: "Stop for the time being, and bear the unbearable."
