The porter's song is a folk song that feels very similar. It is also one of the representative tracks of Xintianyou. The singer's main purpose is to lament his bitter life experience and express his resentment against the unfair society, rather than performing in front of everyone. Its melody line is straight up and down, ups and downs, which is a direct embodiment of the sigh tone. The whole song is like a sigh of complaining, and it is like an accusation and a question to the sky, which reveals the words accumulated in my heart at once. The melody is based on so-do-re-so, which has the typical characteristics of the music. The whole song is not only unrestrained, but also reveals the inner world of the singer with deep and dignified complex feelings, which is of high generality.
"Difficult to recruit workers" is a song complained by the long-term workers in northern Shaanxi. It describes in many paragraphs the specific experience of long-term workers being oppressed. Through the comparison of different treatment between the ruler and the ruled, the social injustice is told. There are sighs in the music (such as "Ouch" in the third section of the score), but the fluctuation is not great. The whole melody is tortuous, flowing and small, which is a typical straightforward expression of emotion.
