People's Daily Online (Some Understanding of Yu Yue): Yu Yue is a general Confucian with a wide range of knowledge and is good at "communication" in academic achievements. As far as his writings are concerned, it seems that the research in specific fields is not as profound as the achievements of later scholars. But as far as Yu Yue is concerned, its academic status is not only reflected in the concrete research results, but also reflected in the inheritance of traditional academics. He himself has repeatedly stressed that his academic orientation is "learning after learning". Yu Yue's three representative works were completed from 1864 to 1868, which had an important influence on the traditional academic development in the next decade or two.
