In real life, the word "behind the ears" is often used to describe some bizarre things. For example, some people look happy on the surface, but in fact they are very painful inside; Some things look expensive, but they are actually very cheap. Abrupt ears can also be used to expose some lies. Sometimes, a person is confident, but in fact he doesn't know what he is talking about. This is a typical deaf ear.
There is an antonym for the ear shun bone, which is called "the ear shun bone". Auditory compliance refers to the fact that the external performance of a person or thing is completely consistent with its internal state. For example, if a person looks confident at ordinary times, but he is actually very confident, then he is an obedient person. Different from the auricular reflex bone, the auricular shun bone represents a real state, not a superficial disguise. However, in some cases, people may deliberately use deaf ears to appear more modest or interesting.
