Who invented backgammon?

Backgammon is one of the traditional black-and-white games that originated in ancient China. Modern backgammon is called "Lian-chu" in Japanese, "Renju" in English, "Gobang" or "FIR" (abbreviation for Five in a Row), also known as "Lian-five", "five in a row", and "five in a row". In English, it is called "Gobang" or "FIR" (abbreviation of Five in a Row), and is also known as "連五子", "五子连", and "串珠", It is also known as "Lianqi", "Wu Zi Lian", "Suan Zhu", "Wu Mu", "Wu Gui", and many other names. Backgammon not only enhances thinking ability and improves intelligence, but is also rich in philosophy and helps to cultivate one's body and mind. Backgammon has not only the obvious characteristics of modern leisure "short, flat and fast", but also the profound learning of classical philosophy "yin and yang"; it has not only the characteristics of simple and easy to learn, which are popular among the people, but also the profound skills and high level international competitions; its Chess culture has a long history, with the mystery of the East and the intuition of the West; it has the concept of "field" and the connection of "points". It is a point of exchange between Chinese and Western cultures and a crystallization of ancient and modern philosophies. Backgammon originated in ancient China, developed in Japan and became popular in Europe. There are two ways of saying about its relationship with Go: one says that it predates Go, and that there was already a game of Go in folklore before "Yao made Go"; the other says that it originated from Go, and that it is an offshoot of the development of Go. It is doubly favored in Chinese culture. In ancient times, backgammon had the same set of pieces as Go, with seventeen vertical and seventeen horizontal pieces. Around the time of the North and South Dynasties in China, Go was introduced to Korea and Japan together with Weiqi. According to Japanese historical documents, ancient Chinese backgammon was introduced to Japan through Goryeo (Korea) during the Genroku period of Japan from 1688 to 1704. The name "Lian-chu" was formalized in the 32nd year of the Meiji era (1899 AD) after a public call for names, meaning "Sun and Moon as a wall, five stars as a series of pearls". From then on, the Lian-Chu activity underwent continuous improvement, mainly in the form of rule changes (i.e. restrictions on the Black side), e.g. in 1899 it was forbidden for Black and White to play "double three"; in 1903 it was forbidden only for Black to play "double three"; In 1912, Black was forced to play "double-three" and was considered to have lost; in 1916, Black was forbidden to play "long link"; in 1918, Black was forbidden to play "four, three, three"; in 1931, Black was forbidden to play "four, three, three"; and in 1931, Black was forbidden to play "four, three, three". "In 1931, it was stipulated that Black was not allowed to play "double four", and the 19×19 Go board was replaced by a 15×15 special board for Lianzhu. At the beginning of this century, backgammon was introduced to Europe and quickly became popular throughout Europe. Through a series of changes, the simple game of backgammon was complicated and standardized, and eventually became what it is today: professional backgammon, as well as an international tournament game.
