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.
It means, don't say that gossip is as deep as a torrent, and don't say that people who are relegated will always sink into mud. Gold panning needs to be filtered thousands of times. Although it is hard, only when the precipitation is exhausted will the shining gold be revealed. This poet has been demoted many times, but he has persistent fighting spirit, optimistic spirit, broad-minded and heroic spirit. Although he has gone through hardships in a remote relegation area, what he can finally show is not useless waste sand, but bright gold. Through the metaphor of concrete images, the poem summarizes the profound feelings gained from self-experience, and firmly believes that those who are hurt by slanderers will know the truth one day and be innocent. The last two sentences can also be used to indicate that learning should be carefully screened and its dross removed in order to get its essence.
