1, one means "nice eyebrows". But this explanation is quite unreasonable, because "eyebrows look good" is not a patent for women, and thick eyebrows and big eyes have always been one of the selection criteria for handsome guys.

2. Another meaning is the causative use of adjectives in ancient Chinese, which means "to make eyebrows beautiful". In other words, it is "trimming eyebrows".

Extended data:

In ancient times, girls had a crush on a handsome man, Xuanzang in The Journey to the West. According to historical records, Xuanzang was "the son of a beautiful girl" and his father Chen Guangrui was "a beautiful girl and an eye".

A girl can be literally understood as: It is well known that a man with a beard is a man, and the word "eyebrow" in this girl with a beard is the word "eyebrow" in the man with a beard. Because the standard of ancient handsome men is white as jade, they all have no beard, so they can't take "beard" and "eyebrow".

The beautiful eyebrow shape should be: the female is narrow and slightly sparse, shaped like a willow leaf or the moon on the third day. This eyebrow shape is beautiful and delicate in women, and is often compared to "willow-bent eyebrows". Men with thick eyebrows are often described as "heavy eyebrows and big eyes", which can show men's masculinity.
