What are the contents of Zhu Men's four poems?

The four poems are: the wine in Zhumen stinks and the road freezes to death. Prosperity and decline are very different, melancholy and indescribable.

It means that in Zhumen, the wine and meat of the rich give off an attractive aroma. On this road, who will bury the poor who froze to death and starved to death? Just a few steps apart, there are two different worlds of sorrow and joy. The injustice in the world fills my heart with grief and indignation, and I can't talk about it any more.

From "From Beijing to Fengxian" by Du Fu in Tang Dynasty.
