Aijk, also known as Harzak. Originated from Uyghur folk. Popular in Xinjiang, such as Maigaiti, Bachu, Avati, Kashgar, Shache and Kuqa.

Ai Czech originated in ancient Persia, and later spread to my country through the "Silk Road". It is very similar to the Jichak of Tibetan Genka, Soviet Uzbek, Turkmen, Tajik and other ethnic groups, especially similar to the Gamanzaqin popular in Turkey and Kashmir.

In the Uyghur folk, it is said that Aijie is the sound made when the door is opened, closed or the wheel axle is turned. It was initially popular in the areas of Hotan, Yarkand and Kashgar in southern Xinjiang, and then gradually spread to all parts of northern and eastern Xinjiang.

In the Qing Dynasty, Aijie was included in the court's Huibu music (that is, Uyghur music), which belonged to the huqin musical instrument. "Lv Lv Zhengyi Post-Edition" records: "There is only one huqin, and the Hui name is 'Halzak'".
