Xun introduction: Xun is the most primitive musical instrument in China. It is shaped like a gourd and has eight small holes on its body. The xun was unearthed from the ancient ruins of Banpo in the eastern suburbs of Xi'an. This 6,000-year-old musical instrument has been rediscovered. Xi'an writer Jia Pingwa likes to play the xun. The sound of the xun is rich and long, with a long aftertaste. Later, many people in Xi'an learned to play xun and started a business selling xun. Walking in front of the academy, you will often hear the sound of xun played by the stall owner selling xun. The xun has almost become an iconic item in Xi'an.
