Eight volumes. It expounds acute diseases such as "latent-qi warm disease" and "new contraction" in the four seasons, with clear legislation, and is one of the important works on warm febrile diseases. Written by Lei Feng (Shaoyi) in the eighth year of Guangxu (1882), and published the following year. Lei once said: "To be a seasonal doctor, one must understand the seasons, know seasonal diseases through the seasons, treat seasonal diseases with seasonal prescriptions, and prevent when they will change, decide when they will resolve, and adjust accordingly." Lei used the eight sentences from the "Suwen?Yin-Yang Response Theory" as a framework: "Winter injury by cold leads to spring warm disease; spring injury by wind leads to summer lienteric diarrhea; summer injury by heat leads to autumn malaria; autumn injury by dampness leads to winter cough." He collected diseases caused by the six qi in the four seasons as the content. First, he discusses the diseases, then the methods of treatment, and also includes prescriptions and clinical cases. At the end of the book, there are 13 additional essays. Volume one discusses "Winter injury by cold leads to spring warm disease," where the author elaborates on the academic insights of latent-qi warm disease; volume two discusses "Spring injury by wind leads to summer lienteric diarrhea," detailing common cold, stomach wind, apoplexy, wind-cold, wind-heat, wind-dampness, cold pestilence, etc., emphasizing "These seven are all new evils injured by the spring season"; volumes three to eight elaborate on latent-qi warm disease and new-contraction warm disease.

The book discusses a total of 72 diseases, proposes more than 60 treatment methods, lists 106 prescriptions, and selects 87 medical cases. Among the seasonal diseases discussed, warm diseases occupy a large proportion. The diagnostic methods proposed by Lei are comprehensive in theory and effective in practice, having a significant influence on later generations. Later, Chen Lianfang wrote "Jiapi Shibing Lun," and He Xiaolian wrote "Zengpi Shibing Lun," further developing Lei's academic foundation. The original edition and various other editions exist, with reprints and typeset editions published after the founding of the People's Republic of China.
