What does Li Shangyin's Ancient Poems of Sui Palace mean?

On the spur of the moment, there is no martial law in the south, and whoever saves the admonition in the spring breeze will be cut by the national officials, half as a barrier and half as a sail.

Note Jiuzhong: The imperial court.

Mud barrier: A blanket covered with mud on a horse.

Explain what a gorgeous fleet and what a luxurious cruise ship. This is all the blood and sweat of the people, satisfying Yang Guang's temporary greed, despite the strong persuasion of ministers. It's just a futile lament. Holiday. This is just a dream.

Yang Di's lewdness and brutality are famous in the history of China. He visited Yangzhou three times and spent a lot of manpower, material resources and financial resources for no reason. His arrogance and lewdness are outrageous. This poem by Li Shangyin mercilessly satirizes and criticizes the actions of Emperor Yang Di through typical examples.
