Cultural Note

In traditional Chinese medicine, understanding the concept of cavities in the body is essential, as practitioners often assess the flow of Qi and the health of organs based on their hollow spaces.

Memory Tip

Imagine a large 'gourd' (sounds like 'guó') that has a hollow inside. The top part of the character 膕 resembles the rounded shape of a gourd, while the bottom part suggests an empty space, symbolizing the cavity.
