《日讲易经解义》十八卷，附《朱子图说》，是清朝牛钮、孙在丰等给康熙皇帝的讲疏基础上进行整理，于康熙二十二年成书，康熙皇帝亲自为之作序。该书大旨在以《易经》贯通《诗》、《书》、《礼》、《乐》，综合诸家注疏，而加以发挥。预言文字方面的解释较少，主要是借治《易经》，研究修身、齐家、治国、平天下的政策方略，于《易》卦阴阳、奇偶、屈伸变化之间，考察人事贞邪，运数盛衰，风俗治乱，目的在于为统治阶级提供统治术。其通经致用的用心是显而易见的。因此，该书对于我们今天工作、学习、生活、修养等方面，仍有一定的启发意义。（Daily Explanations of I Ching has 18 chapters and an attached ZHU Xi Illustration. It was collected on the basis of itemized records of lectures given by Heseri Niuniu and SUN Zaifeng to Kangxi Emperor. Compiled in the 22nd year of Kangxi Empire, the book was then prefaced by the emperor. It aims to contain the essence of Classic of Poetry, Book of Documents, Book of Rites, and Classic of Music in the explanation of I Ching (Book of Changes) and combines notes from different schools to give a new idea. Notes on prophecies are less found in this book. Instead, based on I Ching strategies on self-cultivation, family harmony, state governance and world peace, the book adopts I Ching's theories of eight trigram, yin yang and trigram images, aims to provide the governing class with ruling skills of evaluating the character and behavior of officials, predicting fate change of the state, understanding customs and quelling disturbances. It clearly intends to apply the combined essence in real use, thus may inspire modern life, study, work and self-cultivation.）
