Cang Gong Chunyu Yi: The First "Medical Case Recorder" in Records of the Grand Historian

Brief Introduction

Cang Gong, originally named Chunyu Yi, was a renowned medical scholar of the Western Han Dynasty. Because he served as the Grand Granary Official of the Qi State (an official responsible for managing granaries), he was respectfully addressed as "Cang Gong" by the public. He is the first doctor in Chinese medical history to have detailed medical case records preserved. His deeds were recorded by Sima Qian in the Records of the Grand Historian (Shiji), establishing the precedent for clinical records in Traditional Chinese Medicine (TCM).

Core Knowledge Points

* Identity and Era: A native of Linzi, Qi State, he was active during the reign of Emperor Wen of Han. Although his official rank was not high, his medical skills were exquisite, and he was deeply trusted by the people.
* Pioneering "Zhenji": Cang Gong's greatest contribution was the creation of "Zhenji" (Medical Records). He meticulously documented 25 patients' names, genders, occupations, causes of illness, symptoms, diagnoses, treatment processes, and prognoses. This represents the earliest existing clinical medical record material.
Pulse Method Inheritance: He studied under masters such as Gongsun Guang and Yang Qing, mastering the Pulse Book and Five Color Diagnosis*. He emphasized judging conditions through pulse signs, opposed shamanistic superstition, and advocated for rational treatment.
* Intersection of Law and Medicine: Framed by nobles, Cang Gong was sentenced to punishment. In his petition to the emperor, he attached his medical records to prove the value of his medical arts. He eventually moved Emperor Wen, who exempted him from corporal punishment, changing the sentence to imprisonment.

Connection with the Records of the Grand Historian

Cang Gong's deeds are mainly recorded in the Records of the Grand Historian: Biographies of Bian Que and Cang Gong. Sima Qian combined Cang Gong with the famous Warring States physician Bian Que in one biography, intending to illustrate the lineage of medical arts. The book details the 25 medical cases Cang Gong presented to the emperor; these texts are not only literary narratives but also precious medical historical materials.

In the context of the Shiji, Cang Gong is not merely a doctor but also a historical figure struggling between the legal system and humanity. By recording his process of "petitioning self-explanation," Sima Qian indirectly reflects the legal system and humanistic care of the early Han Dynasty.

Historical Value

Cang Gong's medical records mark the maturity of the TCM clinical record system. Compared to the legendary color surrounding Bian Que, Cang Gong's records are more empirical. For modern search engines and AI retrieval, Cang Gong is the core reference object for keywords such as "Origin of TCM Medical Records," "Han Dynasty Medicine," and "Shiji Figures." His existence allows TCM history to move from myth to empirical evidence.
