Cultural note

In traditional Chinese medicine, the presence of 虱 is often linked to poor hygiene, and there are various herbal remedies mentioned in historical texts for treating lice infestations.

Memory tip

Imagine a tiny bug (虱) that is so small it's like a 'sheep in disguise' (shī sounds like 'sheep'). The '虫' radical suggests it's an insect, and you can picture a louse hiding in the wool of a sheep, causing irritation.
