Wang Shuhe, Sun Simiao, Cheng Wuji, Han Zhihe, Zhu Hu, Xu Shuwei, Pang Anchang, Guo Yong and others have studied "Treatise on Febrile Diseases and Miscellaneous Diseases" successively, each with its own merits. For example, Sun Simiao spoke highly of Zhongjing's "Treatise on Febrile Diseases", but he did not stick to the ancients and made new developments in Zhongjing's theory of Febrile Diseases. He did not classify according to the Six Classics, but classified all the articles of "Treatise on Febrile Diseases" according to the prescriptions and syndromes, which is the so-called "prescriptions and syndromes are in the same article, and the analogies are attached." In this way, everything is organized according to categories, and it is easy to search and use. This method of proving by prescription was later appreciated by Ke Yunbo, Xu Dachun and others. Sun also paid special attention to the application of Zhongjing's three methods of Guizhi, Ephedra and Qinglong. He said: "The general idea of ????my husband's search for prescriptions is only three kinds: one is cinnamon twig, two is ephedra, and the third is green dragon. These three prescriptions can cure typhoid fever." This may be from Wang Shu and "Wind causes injury" "Wei, if the cold hurts the camp, both the camp and the guards will be sick, and the joints will be troubled and painful" is understood. Sun created the theory of the three methods of "hemp, osmanthus, and green dragon", which had a great influence on later generations. Later, the theory of Wuji, Fang Youzhi, and Yu Jiayan was developed into the theory of "three cardinal principles". The two volumes of Sun's Qianjin Yifang (Qianjin Yifang) are the only works on Febrile Diseases that study Treatise on Febrile Diseases in the Tang Dynasty, and are worthy of further study. Since the Ming and Qing Dynasties, those who treat "Treatise on Febrile Diseases" have formed more schools, such as the "re-editing of wrong slips" school by Fang Youzhi, Yu Jiayan, Cheng Xiaoqian and others; the "maintaining old theory" school by Zhang Suichen, Zhang Zhicong, Chen Nianzu and others; Ke Yunbo, Especially in the "syndrome differentiation and treatment" school of Jing, Bao Cheng and others. The prescriptions in "Treatise on Febrile Diseases and Miscellaneous Diseases" are also called "Classic Prescriptions" and are highly respected and still in use.
