Likewise, he was known as the three great master herbalists of the early Qing dynasty, in old age he changed his self-title to 西昌老人(Xī Chāng Lǎo Rén).

Main books and academic thoughts:


 Yu Chang's main works are:《尚論篇》(Shang Lun Pian),《尚論後篇》(Shang Lun Hou Pian),《醫門法律》(Yi Men Fa Lv, or the Principle and Prohibition for Medical profession),《寓意草》(Yu Yi Cao).

 The full name 《尚論篇》(Shang Lun Pian) is 《尚論張仲景傷寒論重編三百九十七法》(Shang Lun Zhang Zhong Jing Shang Han Lun Chong Bian San Bai Jiu Shi Qi Fa). It has 8 volumes, divided into two parts. The first 4 volumes have a title 《尚论编》(Shang Lun Bian, or Edition of Shang Lun), which discusses the treatment of the six channels of Shang Han(the exogenous febrile diseases) in detail, and the last 4 volumes are 《尚論後篇》(Shang Lun Hou Bian, or Post Edition of Shang Lun), which promotes the treatment of spring warm disease, summer dampness, and dampness febrile disease during summer and autumn, and the treatment of warm diseases, and attached various articles of his discussions with disciples.

 Yu Chang is one of the famous herbalists who study Shang Han Lun(the Treatise on Cold-induced Diseases). He believes that although there are exogenous diseases during the four seasons, Zhang Zhongjing has detailed study in Shang Han(cold-induced disease). The method of treating Shang Han(cold-induced diseases) can be changed and used for other exogenous diseases. Therefore, Shang Han is the outline of the four seasonal exogenous diseases. And in "the six channels of Shang Han, the Tai Yang channels is the outline; and in the Tai Yang channels, the outline is wind affect and hurt Wei, cold affect and hurt Ying, wind and cold affect and hurt both Ying and Wei." This forms the main points of Yu Chang's Three Outlines Theory. In the case of wind affect and hurt Wei, the Gui Zhi Tang decoction is applied, in the case cold affect and hurt Ying, the Ma Huang decoction is applied, in the case wind and cold affect and hurt both Ying and Wei, the Da Qing Long Tang decoction is applied. When these decoctions are applied properly, wind and cold pathogens are dispelled immediately without any extra effort. The meaning of Yu's advocacy of the theory of three outlines is that Ma Huang, Gui Zhi, and Da Qing Long decoctions are used to treat the exterior syndromes of Tai Yang. If the exterior syndromes of Tai Yang are treated effectively, there will be no various syndromes and diseases of transmission, and the Shang Han syndromes can be cured in the early stage of illness. Therefore, Yu's theory of three outlines embodies Zhang Zhongjing's thoughts on the early treatment of diseases. Although later generations questions whether this view is in line with Zhongjing's original intention and whether it has clinical practical significance, the positive significance of Yu's theory should be seen.

 Yu Chang has made considerable contributions to the theoretical study of traditional Chinese medicine, not only has his unique experience in the study of Shang Han Lun(the Treatise on Cold-induced Diseases), advocated the theory of the three outlines, but also made great contributions to the basic theoretical issues of traditional Chinese medicine. His views on primordial Qi and autumn dryness are also praised by later generations. In addition, he emphasizes treatment based on syndrome differentiation and advocates standards of diagnosis and treatment, which is also of academic value. His clinical experience is also very rich. The method of treating dysentery and the method of treating obstruction and rejection(anuria and vomiting) are respected by later generations. Therefore, Yu Chang was known as one of the three master herbalists in the early period of the Qing dynasty and became famous for a period.
