It is spread among the partial and Dai people of the Zhuang people. It was originally used by Tianpo (witch) to treat people's disasters and diseases. Later, this witchcraft-like qin, song and dance evolved into a mass entertainment activity, but it is still called singing, playing and dancing.

Legend has it that a long time ago, there was a pair of very good young people in a Zhuang village at the southern foot of the Shiwanda Mountain, a man named Nong Duan and a woman named Nong Ya, who often went up the mountain together to chop wood.

One day, the two of them heard a pleasant "ding dong" sound at the entrance of a cave, followed the sound and saw a water pool, with many small water droplets oozing from the rock wall above and dripping into the pool. The two of them listened to this wonderful and moving music, and they felt refreshed and clear-sighted. The two of them wanted to bring this magical sound back to the cottage and let the villagers share it together. Nongya thought for a while and said, "Why don't we make something that can also make this sound?" So the two found a gourd shell and a wooden pole in the mountains, inserted the wooden pole into the gourd, and stretched the wild vine. The filament strips, as expected, made the sound of "ding ding", just like the sound of the mountain spring of "ding dong".

People in the cottage all clapped their hands and praised it, and an elder even called it "Dingding" by pronunciation.

The villagers still learned to do it, and Dingding soon became popular in the whole village. When the sound of the qin reached the sky, the Jade Emperor sent an angel down to the earth to summon Nong Duan and Nong Ya. Later, they became singers in the sky, playing the qin and singing to the Jade Emperor all day long. In order to eliminate the villagers' thoughts, from the first to the fifteenth day of the first lunar month every year, when the gate of heaven opens, the two of them rush back to the mortal world to gather and dance with the villagers. Usually, when people ask for something, they also burn incense and invite them to come down and sing and dance.

This activity later became a fixed form, named "jumping sky". To this day, every Zhuang nationality traditional festival, partial people hold mass "jumping sky" cultural and entertainment activities. Dingding is the only musical instrument used in this activity, so it is called Tianqin.
