Nodding one's head and lowering one's eyebrows means to bow one's head and tilt it slightly forward, showing respect and modesty towards oneself or others.

The origin of the idiom of nodding one's head and lowering one's eyebrows can be traced back to the traditional culture of ancient China. In ancient China, bowing one's head was a common ceremonial gesture to show respect and modesty to the other person. At the same time, lowering one's eyebrows was also a common expression to show one's respect and modesty. Therefore, the combination of nodding one's head and lowering one's eyebrows formed this idiom to describe a person's modest, respectful, low-key and collected appearance.

In modern Chinese, nodding the head and lowering the eyebrows is still widely used. It can be used not only for self-effacement, but also to describe the attitude or behavior of others. For example, when a person faces an elder or an authority, he or she may display a nodding head and lowered eyebrows as a sign of respect and modesty. Or when a person is receiving praise or appreciation, he or she may also show a nodding head and lowered eyebrows to show that he or she is modest and low-key.
