Jia Xian, a mathematician in the Northern Song Dynasty, created the Jia Xian Triangle. His most famous mathematical achievement is to create a digital schema, that is, "the root graph of the root method", which is actually a positive integer binomial theorem coefficient table, known as China's Pascal Triangle.
Qian Yi (1032 ~113) was originally from Zhejiang, and later settled in Yunzhou (now Dongping County, Shandong Province). His book "The Prescription of Pediatric Medicine" is the earliest monograph on pediatrics in China, and it is known as a classic work on pediatrics of traditional Chinese medicine.

The works have unique insights on paddy field cultivation, land use, soil fertilizer, rice cultivation, sericulture and other aspects in the south of the Yangtze River, and are valuable materials for studying agricultural science in China.
Song ci (1 186 ~ 1249) was born in Jianyang, Fujian. An outstanding forensic scientist in the Southern Song Dynasty, he held judicial positions for a long time. He is the author of Prescription Collection, which is more than 350 years earlier than the western monographs on forensic medicine, and can be called the earliest authoritative work on forensic medicine in the world. The collection of grievances has been translated into Japanese, English, German, French, Dutch and other languages.
Qin (1202 ~ 126 1) was an outstanding mathematician in the Southern Song Dynasty (now Sichuan). He imitated Nine Chapters Arithmetic and wrote Nine Chapters Counting Books, and put forward the solution of higher-order equations, which was more than 800 years earlier than the West. Qin Jiu Shao was one of the greatest mathematicians in the Middle Ages. Nine Chapters Arithmetic marks a peak of ancient mathematics in China.
Guo Shoujing (1231~1316) was a famous scientist, astronomer and hydrologist in Yuan Dynasty. He made 10 kinds of astronomical instruments to accurately observe and calculate the astronomical phenomena. The compiled "chronograph calendar" is 300 years earlier than the current Gregorian calendar. He is a great scientist with many contributions in China and occupies a certain position in the history of world science.
Zhao Youqin (1279 ~ 1368) was a mathematician in Song and Yuan Dynasties. He is the author of the science book A New Book of Peeves. There is an article in this book called "The Scene of a Small Chamber of Secrets", in which the chamber of secrets is a small hole or slit. Zhao Youqin did a series of experiments to study the imaging law of pinhole and the physical phenomena derived from it.
Xu shou (18 18 ~ 1884), a scientist in Qing dynasty, was good at mathematics and engineering technology. Together with contemporary scientist Hua, he built China's first steam engine and wooden hull ship "Huanggu", which is a new achievement in the modern history of science and technology in China. 187 1 year, Xu Shou translated and published six books including Chemical Monitoring Sources.
