Xialiba people:

It originally refers to a popular song in Chu during the Warring States Period. Metaphor is popular literature and art. Idiom story:

Song Yu was an independent civil servant of Chu in the late Warring States period, and never echoed other people's opinions.

the king of Chu heard some bad things about him, so he called Song Yu and asked, "Are you doing something wrong?" Why are many people dissatisfied with you? "

Song Yu replied, "Let me say something first! There is a singer singing in Beijing. At first, the most popular folk song of Chu State, Xialiba People, was sung. At this time, thousands of onlookers sang along. Then he sang the profound "yang a Qiu Lu", followed by only a few hundred people. When he sang the elegant song "Spring Snow" again, there were only dozens of people singing along. Finally, he sang the most advanced song with five tones and six rhythms. Only a few people can sing along. It can be seen that the deeper the song is, the fewer people can sing along! "

Then, Song Yu said, "The same is true among scholars. Those outstanding figures are ambitious and noble, and of course ordinary people will not understand. This is exactly what happened to me! " Hearing Song Yu's remarks, the King of Chu felt very reasonable. There is no further questioning.

The idiom "Spring Snow" and "Xialiba people" came from this. "Yangchun Baixue" was later used to represent elegant literary works, while "Xialiba people" represented popular literary works.
