"Du and Du Lingju have planted more than one hectare of fertile land." The protagonist of Bai Juyi's new Yuefu poem is a native farmer who lives in the suburbs of Chang 'an. He has been farming for generations, guarding more than one hectare of barren land and living a carefree life. China literati's poems are full of romance and elegance. However, few of them consciously regard farmers as the protagonists of their works, and really stand on the side of the working people to express their grievances. At this point, Bai Juyi can be said to be an outstanding one. He was able to speak out for the people in his poems, not because he wanted to be innovative in subject matter, but because of his high sense of responsibility and mission to the political future of the imperial court and the national economy and people's livelihood. The author has turned his attention to people living at the bottom many times. Their lives are miserable and have been neglected. This Du is in trouble and can't extricate himself.
