橐籥（上音託下音藥御注老子云橐[革*匍]袋音敗也俗云[革*匍]袋也籥笛也音狄樂器名也皆虛中能受氣而有聲也）。

橐籥 (bellows and flute): The upper is pronounced *tuó* (音託); the lower is pronounced *yuè* (音藥). The Imperial Commentary on the *Laozi* says: "A 橐 is a leather blower bag (囊袋, pronounced *bài*), popularly called a [革*匍]袋. A 籥 is a flute (笛, pronounced *dí*), the name of a musical instrument. Both are hollow inside, able to receive air and produce sound."
