Su Shi
Although political bickering and opposition usually split ministers of court into rivaling groups, there were moments of non-partisanship and cooperation from both sides. For example, although the prominent scientist and statesman Shen Kuo (1031–1095) was one of Wang Anshi's most trusted associates and political allies, Shen nonetheless befriended Su Shi. Su Shi was aware that it was Shen Kuo who, as regional inspector of Zhejiang, presented Su Shi's poetry to the court sometime between 1073 and 1075 with concern that it expressed abusive and hateful sentiments against the Song court. It was these poetry pieces that Li Ding and Shu Dan later utilized in order to instigate a law case against Su Shi, although until that point Su Shi did not think much of Shen Kuo's actions in bringing the poetry to light.
