Five pieces is one of the traditional black-and-white games originating in ancient China. Modern backgammon is called "Lian-chu" in Japanese, "Renju" in English, and "Gobang" or "FIR" (abbreviation of Five in a Row) in English, and is also known as "Lian-five-zi", "five-zi-lian", "string of beads", "five-eyes", "five eyes", "five eyes", "five frames", etc. It is a traditional Chinese game of black-and-white that originated in ancient China.

Five pieces can not only enhance thinking ability and improve intelligence, but also rich in philosophy, which helps to cultivate one's body and temperament. 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 simple and easy-to-learn characteristics, 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; there is not only the concept of "field", but also the connection of "dots". It is a point of exchange between Chinese and Western cultures and a crystallization of ancient and modern philosophies.

Go 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 a folk game of backgammon long 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 According to Japanese historical documents, ancient Chinese backgammon was introduced to Japan through Goryeo (Korea) during the Genroku period of Japan from 1688 to 1704.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". Since then, the Lian-Chu activity has undergone continuous improvements, mainly changes in the rules (i.e. restrictions on the black player), for example, in 1899 it was forbidden for both black and white to play "double-three"; in 1903 it was forbidden only for black to play "double-three"; in 1912 it was stipulated that if black was forced to play "double-three" it would be considered as a loss; in 1916 it was stipulated that black was not allowed to play "long-links"; and in 1918 it was forbidden to play "four, three, three" for black. In 1916, it was stipulated that Black was not allowed to play "Long Lian"; in 1918, it was stipulated that Black was not allowed to play "Four, Three, Three"; in 1931, it was stipulated that Black was not allowed to play "Double Four", and it was also stipulated that the 19×19 Weiqi board should be replaced by a 15×15 Lianzhu board. 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 the professional backgammon of today, as well as a kind of international tournament chess.
