These spinning bamboo sections made a "whoo-whoo" sound, and when everyone young and old had their "earth bull tops" spinning at the same time, the sounds being emitted from the bamboo-some at higher pitches, some lower, some clear and some dull-combined into an "earth bull symphony." The idea was that the earth bull would be so fascinated that it would forget to turn over.
當大小不一的「地牛」同時轉動、竹聲或高或低、或清脆或渾厚，宛如一首「地牛交響曲」，果真讓地牛聞之入迷，忘記翻身呢。
