This article deals with the internal context of philosophy of two books- ”Commentary of Dao Der Zhen Jingand” and ”Significance of Zhuang Zi” written by Lu Hui Qing (呂惠卿). The purpose of the discourse in these commentaries is to gain the legitimacy of reform by initiating or producing a metaphysical system. As an important member of the XI-Ning reform (also as one member of Xinxue in North Sung Dynasty), Lu Hui Qing, through the activity of making commentaries of the Taoist texts, declared the core political philosophy of change of the political group to which he belongs. Through the commentaries, he discussed the dialectical relationship between ”classics” and ”change.” And he made further discussions into the three domains what dwelled in the complex relations seen in ”The Way and the mass,” ”Change versus Permanence” and ”the methodology of governance.”He emphasized that changes can be normal and have the legitimacy just under the qualification by following the great rule (Tao or permanence). There won't be any variations that should alter the ultimate. And this is valid not only in the sphere of daily living, but also valid in the sphere of governing. In turn, these intellectuals as the core of the emerging bureaucratic, through this ”scriptures postil the commentators” style, revealed their political ideas, strengthened their influence and shared power with the emperor. And all of these had formed a different type of state comparing with that of Sui-Tang Empire.
