What words can be used to describe traditional folk culture, such as folk songs in northern Shaanxi and so on?

The tragic charm of folk songs in northern Shaanxi. In the past, the people in northern Shaanxi suffered from natural disasters and geographical environment, and were squeezed by man-made disasters, local tyrants and evil gentry, tyrants and local ruffians, and powerful families. People live in dire straits. Old people often mention that the drought in northern Shaanxi in the seventeenth year of the Republic of China (1928) was a once-in-a-century and creepy. The next spring, the grass roots were cut off, leaving the elm tree as a bachelor. The miserable dead man was lying on the side of the road. There is a folk proverb: "People eat people, dogs eat dogs, and Lao Zi and his son don't care." The people of northern Shaanxi are fighting, struggling and surviving in extremely difficult life. Go to the grassland in the north, follow the folk song "Go West", and flee to Yan 'an area in the south, seeking a paradise of "beautiful scenery, full of cattle and sheep". Refugees who fled the country, including Li Youyuan, who wrote the world-famous Dongfanghong, sang folk songs while walking and wrote Go South. Similarly, ballads such as "Hard to Find a Job", "A Bachelor Crys for His Wife" and "A Little Widow Goes to the Grave" are all sung with the beauty of sadness, desolation, sadness and sorrow. This sad charm, whether the singer or the listener, is integrated and infected by the sad charm in the song, resulting in spiritual sorrow and spiritual * * *.
