苏辙
Su Zhe was good at writing political comments and historical essays. For example, he had written in book 'xinlun' (新论) ): "In modern society, management can not lead to peace, disarray can not lead to destroy, the rules are not so clear that it wouldn't work and there are no revolution but many social problems." (當今天下之事, 治而不至于安, 亂而不至于危, 紀綱粗立而不舉, 無急變而有緩病.)
