Glass gebang

"Glass Gebang" is a kind of organ made of thin glass, which is produced in Qincun, Jiaocheng, near Taiyuan. It is a kind of children's toy around the Spring Festival in Taiyuan. It has a large head, a flat round shape, a slender tube in the middle, and is blown by the mouth. The extremely thin glass makes the sound of "beep, beep" under the agitation of airflow, which is crisp and pleasant, and is very popular among children. Every Spring Festival, marketing is a fad.
