Meanings

In ancient Chinese, '虫' (chóng) initially referred to venomous snakes, originating from '虺' (huǐ), a type of venomous serpent.
Over time, the term expanded to refer to all types of insects and small creatures.
In ancient literature, '虫' was also used to describe all animals. For instance, in the famous novel 'Water Margin,' tigers were referred to as '大虫' (dà chóng).
In modern usage, '虫' can metaphorically describe someone obsessed with something, like '书虫' (shū chóng) for bookworms.
