Ten years of life and death are so vast that I cannot forget them without thinking about them. Ten years of traces have left the mortal world, and looking back at the green mountains, I fall into dreams.
Ten years of life and death are blurred, without thinking and forgetting. It means that it has been ten years since we were separated as husband and wife, and I can't bear to miss you. But it’s unforgettable in the end. From "Jiang Chengzi·Dreams on the Night of the 20th Day of the First Month of Yimao" In order to mourn my wife, ten years have passed and I still miss my wife.
After ten years of traces in the world of mortals, I look back on the green mountains and fall into a dream. It comes from "Returning to Hermitage" by Chen Tuan in the Song Dynasty, which means that after ten years of travel, there is only one green mountain that I have visited, and it often appears in my dreams. It shows that worldly things have become like a passing cloud, showing the poet's willingness to retreat into seclusion and practice Taoism.
