The word 绑匪 is formed by combining two characters: 绑 (bǎng), which means "to bind" or "to tie", and 匪 (fěi), which means "bandit" or "outlaw". The character 绑 provides the core action, and 匪 provides the identity of the person performing it. Visually and conceptually, they merge to create the direct and vivid image of a "binding bandit", which precisely defines a kidnapper or someone who takes a person by force.
