Judging from Du Fu's "The Play is a Six-quatrain, Part Two", Wang Yang and Luo Lu at that time were both frivolous. After the life of your generation has all turned to dust, nothing will hurt the torrent flowing to the endless river. "
Explanation: The styles of four poets, Wang, Yang, Lu and Luo, were popular at that time. Some frivolous people laugh at them and talk endlessly. You people who laugh at others have long since disappeared. The poems of the four great poets, however, are as enduring as the Yangtze River and will never be affected by your slander. Today, those who oppose the truth, destroy ethics and morality, and attempt to slander history and culture are described in two poems: "Ercao's name is ruined, and rivers are ruined forever". In the end, they are all defeated and ruined. A just cause, like the Yangtze River, will wash away all the sludge and muddy water with an avalanche, rolling forward endlessly.
"Play is six quatrains" was written by Du Fu in response to the habit of some people in the literary world at that time who valued the past and despised the present. It embodies Du Fu's literary criticism view of opposing the good old and not the present.
