The origin of three-dimensional line

It is generally believed that Sanxian originated in China and was formed around15th century. China's traditional musical instrument Sanxian passed through Ryukyu Kingdom (now Okinawa), resulting in the early Okinawa Sanxian, which was later spread to Japan and gradually formed. Influenced by the local Sanwei Line, the early Okinawa Third Line was improved to the present Okinawa Third Line.

Note: In the traditional Japanese music circle, "Sanwei Line" is sometimes directly called "Three Roots", while the national musical instrument "Sanxian" in China is directly transliterated as "Sanxian". But in Chinese, because only using Chinese characters will confuse the two, Japanese national musical instruments are generally called "Sanwei Line".

Note: Ryukyu Third Line is a unique plucked instrument in Ryukyu Islands, which consists of three parts: the head, the neck and the body. Because the sides of the body are covered with snake skin, it is also called snake skin line or snake flavor line. It's different from Japanese Sanxian.
