The Vietnamese word "cạp nong" refers to a specific type of snake known as the "viper." It is often associated with being venomous and can be found in various regions.
In more advanced contexts, "cạp nong" can be used in discussions about biodiversity, wildlife conservation, or even in folklore and traditional medicine, as some people believe in the medicinal properties of snake venom.
While "cạp nong" primarily refers to a type of snake, in some contexts, it may also metaphorically describe someone who is dangerous or untrustworthy, similar to how one might use the term "snake" in English.
