何庆勇

He Qingyong is a Chinese medicine author whose works focus on the clinical study and teaching of classical formulas (jingfang). Seven of his titles are held in this collection, commonly classified under medicine. Representative works include Daytime Practice, Nighttime Reading: Understanding Shanghan Lun Through Formula-Pattern Differentiation; Lectures on the “Associated Formulas–Formula Patterns–Main Patterns” of Shanghan Lun; and He Qingyong’s Clinical Records of Classical Formulas in Treating Difficult and Critical Cases. Public information about him is limited, and details such as his birthplace, dates of birth and death, education, and teachers are unknown. Judging from his titles and subject matter, he writes consistently on formula-pattern differentiation in the Shanghan Lun and Jinkui Yaolue, explaining the correspondence between associated formulas and formula patterns while recording clinical cases in which classical formulas are used for difficult and critical illnesses. Some of these works form the series Daytime Practice, Nighttime Reading, including a revised edition. His books are aimed at clinical practitioners and learners of classical formulas, and emphasize connecting canonical texts, diagnostic reasoning, and concrete case records, giving his writing a clear, series-based character among reference works on jingfang study and clinical practice.
