Compiling and classifying medical writings
Wang's surviving reputation is closely tied to organizing earlier medical knowledge. The preface to the Maijing describes pulses that resemble one another and distinguishes knowing a name from recognizing a condition by touch. Difficult or scattered texts, it argues, encouraged students to rely on partial interpretations.
The ten-volume compilation gathered earlier medical discussions and recorded differences among authorities. Collection was accompanied by selection and classification, bringing observations and treatment discussions into a form that could be consulted by category. Wang's association with Zhang Zhongjing's writings belongs within this history of copying, collecting and rearranging medical texts.
Making tactile observations comparable
The first chapter lists twenty-four pulse categories, including floating, deep, hidden, wiry and tight. Light and heavy pressure distinguish some categories, while images of a bowstring or twisted cord convey others. The text also groups similar pulses to identify differences within apparently related sensations.
Later chapters discuss time of examination and the wrist positions known as cun, guan and chi, relating pulses to appearance, sounds and other signs. This arrangement sought to turn individual tactile experience into a vocabulary that could be taught and compared. Its classifications preserve the explanatory framework of historical medicine.

Later debate over the Shanghan Lun
Medical histories credit Wang with collecting and arranging Zhang Zhongjing's writings. From the Ming commentator Fang Youzhi onward, some interpreters blamed him for disturbing the received order and proposed reconstruction. Others disputed that attribution. The question affected both how readers approached the classic and how they judged the compiler.
In a 2019 essay, Qian Chaochen drew on Zhang Taiyan's textual arguments, including annotations recording what an earlier text said or expressing doubt about attribution. He treated these as evidence that editorial uncertainty was marked openly. This is an argument from textual witnesses and notes, requiring the received passages, annotations and later rearrangements to be examined separately.
