What is the theme of the short line?

Short songs, a genre of poetry, are two poems written by Cao Cao, a politician and writer at the end of the Eastern Han Dynasty, with the theme of ancient Yuefu. The first poem expresses the poet's desire for virtue and ambition to unify the world through the singing of banquets. The second song praises Zhou Wenwang, Qi Huangong and Jin Wengong's adherence to the history of the Minister's Day, indicating that they only have the ambition to help the Han Dynasty, but have no intention of representing the Han Dynasty's independence.

Songlines

Lipper

The days are too short, and a hundred years have passed quickly.

The size of the sky and the length of the land cannot be robbed.

Even with the famous fairy mago, her hair is half white.

The weather plays Tuho with Jade Girl, and she laughs once every once in a while, and laughs a hundred billion times.

I want to take Liulong back to the car and hang Fusang.

With the help of the Big Dipper, every dragon advised them to drink a glass of wine, so they all fell asleep and couldn't stay awake.

Prosperity is not my wish, I just want to keep time for the people and stay young forever.
