This song is Bai Juyi's "To Tang Sheng". The full text is: Jia Yi cries about current affairs, Ruan Ji cries about Lu Qi. Tang Sheng also cried today, and different generations share the same sorrow. Who was born in Tang Dynasty? He was fifty cold and hungry. If you are not sad, you will have no food in your mouth, and if you are not sad, you will have no clothes on your body. The sadness is about loyalty and righteousness, and when the sadness is severe, we cry. On the day when the Taiwei attacked the thieves, when the Minister scolded the thieves. The official died of the fierce bandits and remonstrated with the barbarians. Every time I see something like this, I burst into tears. Often after hearing about its custom, the common people may still think it is wrong. Lianjun's head is half white, but his ambition is not weak. I am also your disciple, why did you do so? Unable to cry out loud, I turned it into a Yuefu poem. There is no empty space in every article, and every sentence must be in order. People who have great merits say that they are admonished, but those who suffer from great pains are criticized by others. It’s not just about having high palace rules, but it’s not about having wonderful writing. Wei Song makes people sick, and I hope the emperor will know about it. Before the emperor knew about it, he was willing to accept the ridicule of the people of the time. The taste of the medicine is bitter and the sound of the piano is thin. Not afraid of the wrath of power, he is also willing to be ridiculed by his relatives and friends. The man was so helpless that he called himself a crazy man. Whenever a group of thieves take a breath, or they encounter clouds and fog. But since I sing loudly, I will be humbled by my concubines for a few days. Although singing and crying have different names, their feelings have the same meaning. I send you thirty chapters and cry with you.
