Qian Yi - a figure in the Lu Southwest dialect miscellaneous conversation

Qian Yi, the word Zhongyang. Born in 1032 AD, died in 1113 AD, his ancestral home was Qiantang, Zhejiang, and his grandfather moved to Dongping Yun Prefecture (now Yuncheng County, Heze City, Shandong) during the Song Dynasty, and was the first famous pediatric expert in the history of medicine in China. His apprentice Yan Jizhong sorted out his theories, medical cases and prescriptions and compiled them into the "Pediatric Medicine Certificate Straight Recipe", which is the earliest surviving pediatric monograph in China and the earliest pediatric monograph in the world.

Qian Yi's proposition that "if you want to get a child's safety, you often have to be hungry and cold", which means that the child's internal organs are delicate, the digestion and absorption function is not perfect, and if you keep seven points full, the internal organs are not easily damaged. For example, the elderly chase after the child to feed, this is not a good practice. The child is not willing to eat, do not eat well; the child is hungry, of course, when shouting "hungry", let the child eat. There are also children Yuanyang sufficient nature active, if the clothes are too warm, easy to sweat cold, resulting in colds and flus, therefore, let the children in the "seven points warm" environment, it is not easy to get cold and fever. He also advocated that adults should not eat too much and dress too warmly. Because too much food for exquisite things or food-loving foods will make the human body not consume enough various nutrients, make people thin, or eat too much will cause patients or obesity. His "maintenance and health" method has been confirmed by future generations to be a scientific and effective health care method.

Qian Yi's life, the most prominent place in medicine, is "single-minded for the profession, forty years", specializing in pediatrics. He collected and studied the ancient and modern pediatric materials one by one. In particular, the pediatric pulse method, diagnosis of disease evidence, and the treatment methods of epilepsy, chancre, fire dan (i.e., erysipelas), and miscellaneous evidence mentioned in the "Cranial Fontanelle Sutra" are studied. He also used the enlightenment of the "pure yang of children" in the "Cranial Fontanelle Classic", combined with his own clinical practice on the basis of zhang Zhongjing's summary of dialectical treatment, and explored a set of "five visceral dialectics" methods adapted to children. Later, he went to the capital to cure the illness of the daughter of the eldest princess, so he was awarded the official position of "medicine" in the Hanlin Medical Official's Hospital; the prince suffered from convulsions, Qian Yi cured him with "loess soup", and Emperor Shenzong of the Northern Song Dynasty promoted him to the rank of Tai Doctor and gave him a fish charm and purple clothes decorated with gold.

Based on his rich experience in witnessing, he wrote five volumes of "On Typhoid Fever" and "On Infants and Children" in 100 articles, but all of them were scattered and not passed on. The existing "Pediatric Drug Certificate Direct Recipe" is the earliest record of the identification of measles and the treatment of whooping cough; it is also the earliest to identify smallpox, measles and chickenpox from the characteristics of the rash; it describes a variety of primary diseases and pediatric developmental and nutritional disorders, as well as a variety of well-known and effective prescriptions; and also established the earliest pediatric medical records in China. This book is listed as a must-read book for the study of pediatrics, and the "Outline of the Catalogue of the Four Libraries" calls Qian Yi's book "the originator of the juvenile family, and posterity has its introduction, and often has the merit of rejuvenation.".
