If modern people have symptoms such as nasal congestion, runny nose or cough, it is commonly called "cold", but in ancient Chinese medicine texts, there has never been a record of the word "cold", which shows that it is not actually a medical term, from Shen Kuo's "Mengxi Pen Talk", it is known that the word was originally an official language, which was an excuse for officials to take leave.
During the Song Dynasty, there were ZhaowenGuan, Shiguan, Jixianyuan and Secret Cabinets, Longtu Pavilion and other book collection institutions collectively known as the "Three Pavilions", commonly known as the "Pavilion Pavilion", which were mainly in charge of matters such as books and scriptures and the compilation of national history, according to regulations, the Pavilion needed to have an official responsible for staying behind every night to prevent books from being stolen.
In the "Mengxi Pen Talk" written by the Northern Song Dynasty scientist Shen Kuo, there is a relevant record, "The pavilion rotates the school officer to stay directly every night, and if there is no reason, it is a false night, which is called 'open accommodation'." According to the story, the stay must not pass through four, and it must be admitted to the fifth day. In the case of open-ended accommodation, for example, in the book of the famous position of the suzhou calendar: "Restless stomach, free of accommodation." The Guguan Pavilion Calendar, which is said to be called the "Bad Belly Calendar", refers to the fact that if an official cannot stay on duty, this is called "Open Stay", and the Open House must not exceed 4 days, and on the 5th day, it must enter the house.
Until the Southern Song Dynasty, the tai student Chen Hu was holding a position in the pavilion at that time, one day he planned to take a leave of absence, but instead of writing "belly restlessness, free of accommodation" on the leave book, but wrote "feeling the wind" on his own, he once recorded his creativity in the book "The Continuation of the Old Age", "Yu is too learned to live, take a leave of absence, set up a book on the front porch, the book cloud "sense of the wind", then the "bad belly calendar" can be on the "sense of the wind book", proudly claiming that the "sense of the wind book" and the "bad belly calendar" echo each other.
Why Chen Hu will create the word "sense of wind", in fact, there is also a history, there was a School of Traditional Chinese Medicine "Yongjia Medical School", the founder Chen Wuxue has a medical book "Three Causes", the disease is divided into internal causes, external causes and not internal and external causes according to the source of the disease, of which the external causes are called "six obscenities", including wind, cold, summer, wet, dry, fire, Chen Hu will be associated with the "wind" of the first cause of the cause, and add the word "sense" in front of the word, that is, the meaning of being blown by the wind to catch a cold, so it is called "sense of wind".
In the Ming and Qing dynasties, the sense of wind evolved into a cold, and became a pretext for officials to take leave, because "risk" has a revealing meaning, "cold" is the meaning of still carrying illness after feeling the wind, in addition, the "Tea Room Cong Banknote" written by the late Qing Dynasty Master Yu Fan once mentioned, "According to the current system of officials to ask for leave, the cold is the excuse, when the Song Dynasty 'Sense Wind Book' will will", the cold has gradually become a daily colloquial language, and the word cold can also be seen in Ming and Qing novels, such as "Water Margin" "The little man in the Road cold and cold, has not been cured, and sent to fight"; "The Surprise of the First Shooting" "The old mother is old again, and there are some colds and dews on the ship in the morning and evening, and she can't afford to be sick."
