Four-stringed Hu, the Zhuang nationality bow and stringed musical instrument. The timbre is rich and used for folk song accompaniment. Popular in Tian'e County, Hechi Area, Guangxi Zhuang Autonomous Region.

A long, long time ago, there was a handsome boy named Shan Lang and a girl named Na Ying in the Bouyei tribe. They grew up as childhood sweethearts, grew up together, and fell in love with each other. When they proposed to get married, both parents were staunchly against it. Because Naying's family has food and clothing, Shanlang's family is very poor.

So, the parents thought of a way to embarrass them. Divide a pair of stone mills between Shan Lang and Naying, one for the top plate and one for the bottom plate. Tell them to get to the top of the two mountains and roll down at the same time. If the two mills can be put together, let them marry. After they did as their parents asked, the two plates of stone mills collided and shattered at the foot of the mountain. They knew they couldn't become a family, so they both jumped off the top of the mountain and died.

The parents of the two families used broken stones to build a tomb at the foot of the two mountains. There is a small ditch in the middle. A few years later, a bamboo tree grew on each of the two graves. The bamboo grows day by day, and the bamboo gradually stretches from both sides of the ditch to the middle, and finally pulls together. Whenever the wind blows and shakes, it makes a very pleasant sound, like a Bouyei love song.

Later, a young man named Tailang cut down bamboo to make a four-stringed beard. He compiled the love story of Shan Lang and Naying into many love songs, and sang them to people with Si Xian Hu. A touching love story is intertwined with the sound of four-stringed hustle. The beautiful four-stringed Hu sound attracted ten beautiful girls. They were fascinated by this handsome young man, and they all wanted to marry him. He put forward a condition that whoever can sing best with his four-stringed hu accompanist, he agreed to marry her. After ten days and ten nights of singing, a girl named Nami finally won the boy's love.

Since then, the Bouyei people have been using the four-stringed hula to play beautiful Bouyei love songs to express their sincere love.
