When it comes to the disease, we are not unfamiliar, in some literary works or some wild history will appear in this word, such as Lao She’s Camel Xiangzi is finally got the disease, but also some folk history that the Qing Dynasty’s Tongzhi Emperor also died of the disease. So what exactly is the disease? Is it a name for one disease, or is it a generic term for several diseases? The term “flower and willow” originated from Li Bai’s poem, “The night of the flow of the Lang to the judge Xin”: “In the past, in Chang’an, drunken flowers and willows, five noblemen and seven noblemen were drunk with the same cup”. The word “flowers and willows” here refers to places of pleasure. Later on, the “flowers and willows” as the pleasure-seeking (prostitutes) as a proxy, because of sexually transmitted diseases occur in the case of prostitution, so to the late Qing Dynasty, the early Ming Dynasty will be sexually transmitted by such diseases are collectively referred to as “flowers and willow disease”. In the late Qing Dynasty and early Republican period, these diseases were collectively called “philopathies”. At that time, there were many monographs on the research and treatment of philopathies, such as “Philopathies” (translated by John Garcia [U.S.], 1872), “Philopathies Treatment” (translated by Ding Fubo, 1909), “Philopathies Easy to Know” (translated by Li Gongyan, 1919), “Latest Philopathies Diagnosis and Treatment” (translated by Yao Bolin, written by Yamada Honglun, 1929), “Philopathies Syphilis Gonorrhea and Methods and Treatment (Yin Jian, 1933), “The New Edition of Floridology” (Zhang Kecheng, 1934), “Modern Floridology” (Mou Hong Yi, 1935), etc. In 1890, the British missionary Meitengen set up the first dermatology department in Hangzhou Guangji Hospital, which was the first dermatology department in Chinese hospitals. In 1894, the Beiyang Medical College opened a course on dermatology and philodermatology, and the Beiyang Hospital set up a dermatology and philodermatology department to treat patients with skin diseases. This was the first dermatology department established by Chinese people with self-reliance. After the founding of New China, the state began to close brothels, outlaw the prostitution system, and actively carry out the prevention and treatment of venereal diseases. 1954, the Central Institute of Skin and Venereal Diseases was established in Beijing, and after liberation, through the attention of government departments at all levels, venereal diseases were basically eliminated in China in the early 1960s, and in 1961, the Ministry of Health requested hospitals to rename the Department of Skin and Flower Diseases as the Department of Dermatology. At this point, the term phimosis was officially replaced by venereal disease and became a historical term. In 1964, Hu Chuangui, then president of Beijing Medical College and director of the Central Institute of Dermatological and Venereal Diseases, read a paper entitled “The Control and Eradication of Syphilis in China” at a scientific symposium in Beijing, arguing with informative data that it took only 15 years after the founding of the People’s Republic of China to achieve the remarkable achievement of basic eradication of venereal diseases, which was highly appreciated and praised by international public opinion. Since the 1980s, various reasons have led to the re-emergence of STDs in China, with the number of cases rising and becoming a major social nuisance. The dermatology departments of major hospitals have been changed to “dermatology and venereal disease departments”. The term “phimosis” disappeared, but “phimosis” is still around, including the newly discovered AIDS in the 1980s, which has become a global threat to sexually transmitted diseases.
