It is natural for people to think that the increasing popularity of seeking medical treatment and the continuous development of medicine are the important embodiment of the progress of human civilization. Generally speaking, the progress of medical technology and the abundance of medical resources mean that the phenomenon of self-treatment is reduced. However, this study of Chinese medical history found that it had always been a common choice to seek self-treatment for people in all social classes, from literati and bureaucrats to ordinary people in remote mountainous areas, especially during the Ming and Qing Dynasties in China. Such records can be seen especially when looking through historical materials such as medical books, local chronicles, genealogies, notes, and anthologies. Although medical skills in Ming-Qing era were more developed than previous eras and the local medical resources were more abundant, from ordinary people in remote areas to elite groups such as literati and officials, people often regarded self-treatment as a basic choice when they or their family members fell ill, no matter whether they had the ability or the opportunity to delay medical treatment. This article aims to explore the logic and root behind this seemingly contradictory phenomenon. Therefore, this research first raises the question: what accounted for this seemingly contradictory phenomenon? In response to this question, this study confirms the following: Firstly, low barriers to entry and high rewards drove people of varying qualifications into the medical profession, and good doctors were hard to find; thus, self-treatment was no worse than the alternatives. Secondly, in the Ming-Qing dynasties, Confucian physicians tended to write more practical prescriptions, which gave many people the opportunity to improve their own medical knowledge and provided great convenience for self-treatment. Thirdly, since the mid-Ming Dynasty, the high medical cost had caused serious difficulties for ordinary people to seek professional medical care, so they tried their best to save themselves when they fell ill. On this basis, this study further found that the deeper reason for this phenomenon lies in the incoordination between the high degree of daily life style of traditional medical treatment and the corresponding low degree of medical specialization and professionalism. Then, this leads to another question: is this incongruity a historical norm or a product of a certain historical stage? This article argues that during the Ming-Qing era, in the macro trend, the two showed a competitive relationship. However, in the context of a broader and more microscopic time and space, is this competitive relationship valid? Especially at present, chronic non-communicable diseases are becoming the biggest threat to human health. With the professional development of medical technology, the trend of medical life-style has also become a reasonable way to fill the gap from highly authoritative medical treatment and take on the responsibilities of their own health. This kind of medical specialization and life-style seems to be developing in parallel. Therefore, it can be concluded that the dissonance between the two is only the product of a certain historical period. Finally, this study raises another relevant question: what are the social and cultural implications behind the parallel development of medical life and specialization? This is a question to be answered in future research on the topic.
