The whole poem is as follows:
Mo Tao's slanderers are as deep as waves, and Mo Yan's guests are as heavy as sand.
Although it is hard, it is difficult to blow out crazy sand when it is not golden.
The meaning of this poem is: don't say that slanderers are like stormy waves, and don't say that relegated people are buried in water like mud. After thousands of times of filtration and hardships, we can finally wash out all the sediment and get glittering gold.
Extended data:
"Mo Tao's rumors are as deep as waves, and Mo Yan's guests are as heavy as sand." In these two poems, the poet shows in a firm tone that it is not inevitable that slanderers are "as deep as waves" and "as heavy as sand". In other words, even if the rumors are as deep as the waves, they may not be "sand-heavy" to attract guests. Not all people who are unjustly exiled will sink to the bottom of the river like sediment, and some people will struggle.
"Although it is difficult, it is difficult to blow up the yellow sand before it reaches the gold." The literal meaning of these two poems seems to be that people who write about gold panning have to go through "thousands of times" and filter out all the sediment before they can get gold, which is about the hardships of gold panning people.
But in this poem, the poet is trying to show his mind, even if the slanderers framed him, so that those innocent and upright loyal ministers suffered injustice, were dismissed from office, demoted, expelled from the court and relegated to other places.
However, they will not sink into the sediment of reality and will not change their original intention. After suffering, you will eventually clear your grievances and be innocent, just like gold panning. Although they have gone through hardships, they will eventually "blow out wild sand" and gold will shine sooner or later.
If the work is related to Liu Yuxi's political career, slanderous remarks obviously refer to the admonition of party member who vilifies Yongzheng and the rumors that criticize him in every way. In the first two sentences of his poem, he has clearly expressed his strong will, and then he used the specific matter of panning for gold in the sand to connect with the body of justice. After all kinds of hardships, he will finally stand up to them and show his true colors as a hero, which is universally acknowledged.
The work summarizes the poet's profound feelings through concrete images, and also gives philosophical enlightenment to future generations.
