I wonder if there was a toy called "glass horn" in the past?

Folk traditional toys, commonly known as "glazed speakers".

Glass horns are formed by blowing and drawing molten glass. The small horn is about 30 cm long and the large horn is about 120 cm long. Blow and suck when playing, and the sound is crisp and loud. It was popular in the Qing Dynasty. In the past, it was the best-selling children's book at Beijing Temple Fair.

Temple fairs in Beijing can still be seen at present.
