Listen to the thousand-year-old Hexi Bao scroll. Hexi Bao scroll is a traditional folk chanting folk literature developed on the basis of Dunhuang's changing texts, common sayings and Song Dynasty's scriptures. Baojuan was produced in large numbers in the Ming and Qing dynasties and prevailed in many places in the country. In the vast rural areas of Hexi area in Gansu today, Baojuan still has a vigorous vitality. In 2006, Hexi Baojuan was listed in the first batch of national intangible cultural heritage lists. The Baozhan in Hexi has four types of Buddhism, historical story, myth and legend, and allegory, the content reflects the social life of the people, and the theme condemns the perversity and murder, promoting filial piety and good deeds. The main form of the Hexi Bao Roll is the combination of rhyme and white during the lectern singing, and the main means of attracting listeners to actively participate in singing is "taking the sound of Buddha". Vernacular is a performance method used by the scroll to narrate the storyline, explain the development of the event, describe the relationship between the characters, and point out the time and place, and express it in the form of "talking" or "talking". The rhyme is to convey good and evil, promote the development of the storyline, express love and hate, and promote the atmosphere, and use the method of "singing" or "singing" to express it. Rhyme and sports treasures blended various tunes, and also added some Liangzhou folk songs, such as "Crying Five More", "Lotus Fall", "Ten Advice People" and so on. According to the investigation, there are about 30 volumes of Liangzhou Bao Roll scripts, mostly woodcuts and manuscripts, and some mimeprints appeared in the early 1980s. There are more than 70 kinds of lyrics and singing voices collected in Jiuquan Bao Roll, and the number of Bao Rolls reaches more than 70 kinds (including the existing list) more than 140 copies. Due to the development of rural economy and the change of living customs, few people have taken the initiative to hold activities to sing Bao Roll. Most of the people who are now over 70 years old are elderly. As this group gradually dies in the future, Hexi Bao Roll will face a crisis of extinction.
