Biwang is a Tibetan bow and stringed musical instrument. Tibetan is also called Biyong, Biyang, Bawang, Ri'aza, Zeze, Zani, etc. due to different dialects. The Han people call it Xianzi, Niujiaohu or Huqin. It has a relatively long history, and its shape is basically the same as that of the Han nationality erhu. It has a bright pronunciation and beautiful timbre.

In ancient Tibet, Biwang was a general term for stringed instruments, and it also included stringed instruments, just as Huqin also included stringed instruments in the early days.

The Tibetan scholar Sakya Pandita Gongga Gyaltsen in the Yuan Dynasty has already recorded Biwang in the murals of the Sakya Monastery in Sakya County, Tibet, built in AD 1037, and there are already images of it. In the Tibetan historical books "Five Bequeathed Teachings" (written at the end of the 13th century) and "Ming Jian of the Lineage of Wang Lineage" (written in the 14th century), the former records that from the 7th to the 9th century AD, there was a biwang in Tibet, and the latter It is described that Princess Wencheng played Biwang to express her feelings after entering Tibet, and the above are all playing the stringed instrument pipa.

It was only in modern times that Biwang was used as a special name for stringed instruments. The Tibetan folk artist Luo Bu Zhandui believes that the Biwang they use originated from the Han nationality area in the mainland, but the date and route of introduction are unknown.

The more famous Biwang music are: "Aji Eat Nama", "Yixueli Luo", "Benzilan Xianzi Diao Eight Songs" and so on.
