A poem ending in honesty

Han Yu bitter cold: Zhuan Xu is not cheap.

Wei Zhuang's Twenty Rhymes of Cui Langzhong's Winter: If you look at the stars, you will feel that Langzhong is expensive, and if you ask the vulgar, you will know that you are too sincere.

Liu Yuxi's "Watching the Drunken Song of Nanxi Niu Gong": If you take off the shackles, you will be humble, but it will not be cheap in the mountains and rivers.
