How did Li Shangyin, a poet in Tang Dynasty, evaluate Yang Di?

Li Shangyin's Sui Palace

His Ziquan Palace has been occupied by clouds, because he will take the whole Yangzhou as his private territory.

If the imperial seal had not been seized by Tang Taizu, he would have set sail long ago.

Fireflies are gone now, leaving the weathered grassland, but they are still perched by weeping willow crows at dusk.

If he met, the world was in chaos, and the later Emperor Chen, do you think they would mention a "Garden Flower"? .

This poem was written by Li Shangyin, a poet in the Tang Dynasty. He satirized Yang Guang, the emperor of the Sui Dynasty. Yang Guang is one of the most dissolute and extravagant "famous" emperors in history. He has been in office for fourteen years, but he has been playing outside for thirteen years, which means that he only stayed in Chang 'an for less than one year. Yang Di built three palaces in Jiangdu (now Yangzhou), which were very luxurious. He traveled to Yangzhou three times before and after, and consumed all the people's oil. Every time he goes out, people all over the country sail for him and pay all the expenses for eating, drinking and having fun. Yang guang is so dissolute that the whole national strength will inevitably decline and the dynasty will inevitably perish.
