Bai people learn advanced culture represented by China culture with an open mind and an inclusive mind. According to Li Yuanyang's Records of Jiajing Dali, as early as the early Western Han Dynasty, two Dali people, Zhang Shu and Sheng Lan, went to Sima Xiangru to study poetry classics. After returning to Dali, Zhang Shu passed on what he had learned to his fellow villagers; Sheng Lan wrote a four-volume literary theory work Fu Xin, which was handed down from generation to generation. During the Sui, Tang and Song Dynasties, Nanzhao and Dali were established successively in Dali, which lasted for more than 500 years. Nanzhao regime has always maintained a close and friendly relationship with the Tang Dynasty. Nanzhao was repeatedly ruled by the Tang Dynasty and sent envoys to the Tang Dynasty to pay tribute. During the period of Dali in Song Dynasty, the local government of Dali had more frequent cultural exchanges with the Song Dynasty and the mainland. According to Fan Chengda, a poet in Song Dynasty, in Gui Ji, Dali people such as Li Guanyinde, Dong Liujin Hei and Zhang Prajna all went to Hengshanzhai for trade. They sold Dali's horses and bought hundreds of books, such as Notes on Selected Works of Five Officials, Notes on Five Classics, Notes after the Spring and Autumn Period, Notes on Three Histories, Notes on Du Da's Materia Medica, Notes on Five Zangs, and Holy Calendar. It is precisely because of the extensive political, economic and cultural exchanges between the two sides that the ancestors of Dali Bai studied and absorbed the advanced Han and Tang cultures, and created the third cultural peak in Yunnan history-Nanzhao Dali culture, which made Dali once the political, economic and cultural center of Yunnan.

After the Yuan, Ming and Qing Dynasties, Dali national culture with Bai as the main body absorbed a lot of Han culture on the basis of inheriting and maintaining its traditional culture, and then merged Han culture with local traditional culture to form a new Dali culture. Dali culture absorbed China culture in the subsequent development process, while maintaining a distinctive national character. Until now, this is related to the cultural core spirit that Dali culture has always maintained, which is not only a reference, but also an absorption, a judgment and a choice. There have been many ethnic exchanges and integrations in Dali history. World religions, such as Buddhism, Taoism, Islam and Christianity, have all spread in the Bai nationality area, but after these religions entered the Bai nationality area, Dali still maintained the local worship of the Lord. Dali culture has not lost its own characteristics under the strong impact of different cultures in the process of contact and exchange with foreign cultures, which is inseparable from the mechanism that Bai culture can integrate different cultures with local cultures into a new Dali national culture. This mechanism is particularly obvious in Bai folk literature.

Bai nationality is a nation that can sing and dance well, and it is also a nation that takes songs as its history. Its oldest form of song and dance is "singing", that is, a kind of music and dance that dances around the fireplace, such as Genesis written by Bai people in Xishan, Eryuan County:

Who can change the sky and the earth?

Pangu and Pan changed the world.

The year of the rat turned into the sky,

The Year of the Ox became land.

The sky is full of clouds,

The land is not satisfied with water.

The land is getting narrower and narrower,

Narrow is not flat.

It's too cold at the top,

Heaven and earth have become?

In the song, it is obvious that the Han myth Pangu started the world, and he was angry and could not touch the poor mountain. The sky is dissatisfied with the northwest, and the ground is dissatisfied with the southeast. Nu Wa refined five-color stones, which made up for the influence of heaven, but it was only a shadow. The whole song is an explanation of the formation of everything in the world by Bai ancestors.

Bai folk songs are obviously sad, and there is no complaint in mourning. The ancestors of the Bai nationality have experienced countless sorrows, but their ancestors have never lost their faith and pursuit of truth, goodness and beauty. They believe in the conscience of heaven and earth and that there is a God who holds the justice of the world. In the traditional culture of China, eternal motifs such as justice conquers evil, good and evil will eventually be rewarded, and human themes such as loving others and giving oneself up for others are widely expressed in Bai folk songs, music and dance, folk sacrifices and folk dramas, in addition to the myths and legends and subjective beliefs mentioned in the first and second parts of this paper.

With the evolution of history, Bai folk music has gradually formed a "big Ben" vocal style including nine boards, three cavities and eighteen tones. Big Ben's minor includes herding sheep, going to the grave, forcing feelings, paying homage, asking about the soul and homesickness. Folk dances include tea ceremony, drunken dance, wine ceremony dance, end-plate toast dance and water delivery dance. It shows the Bai people's views on loyalty, friendship, family, wealth, right and wrong, good and evil, happiness, life and death, marriage and love. Even though there are many concepts in Confucian traditional culture, Bai people have transformed them into a way they can understand, reflected them in a form that they like to see and hear, and turned them into their own culture.

There are many spontaneous mass religious organizations in Bai nationality, such as "Lianchi Association", most of which are composed of Bai elderly women. After work, they engaged in folk religious activities such as chanting scriptures and chanting Buddha, which lasted for thousands of years and played an important role in inheriting Bai culture. Some collected and sorted out hundreds of scriptures recited in Lianchihui, and the multi-culture of Bai nationality with Buddhism, Taoism and Confucianism as the core was reflected in the scriptures. For example, from Pangu's creation, the beginning of the Second Qi Dynasty, the Three Emperors and Five Emperors and everything in the world could not be separated from the reproductive upbringing of Mother Earth (also known as the mother of all things). The Third World Karma Sutra talks about the truth of karma, teaching people to do more good and not to have evil thoughts. The Luo Cha Classic demonstrates the story of "Guanyin conquering Luo Cha" with scripture. The "Top Ten Classic Reports" is about the difficulty for parents to raise their children and teach them how to report their filial piety.

Bai folk opera is an important carrier of inheriting Bai culture. Such as Heqing and Yunlong, the content is very rich. There are not only costume dramas, such as Kongming Opera, Guan Gong Opera and butterfly lovers. There are also pantomime, such as Lv Dongbin and Han Xiangzi. And a new screenwriter who plays the real story. However, the performances are all performed from the perspective of the Bai people, and the forms are all in white tones, with Bai musical instruments (Sanxian, Suona, Erhu, etc. Some places, such as Yunlong folk, also have a set of Facebook created by themselves. Even the costume drama makes the audience look as if it happened in the Bai area, which narrows the distance between the characters and the audience and makes the audience like it more. More importantly, many vivid ideas and creative spirits of the Bai people are integrated into the drama concepts and ideological themes, and the isomorphism with * * * has become the profoundness of Chinese national culture. '

The above-mentioned characteristics of Bai folk literature vividly show that Bai spread the agricultural, handicraft production technology and spiritual culture of the Han nationality in the mainland to other ethnic groups in Yunnan and even people in neighboring countries, promoted the pluralistic development of the Chinese nation and extensive cultural exchanges between China and foreign countries, and made important contributions to the reunification of the motherland and the development of Chinese civilization. In Dali area, various ethnic groups with Bai as the main body have nurtured, derived and developed unique and splendid culture. These cultures have both overall and regional characteristics; It not only contains the commonness of China culture, but also contains and presents the distinctive personality of Dali, region and humanistic environment, which has made important contributions to the formation of "pluralistic integration" of China culture and is a wonderful flower in the world's multicultural gardens. Its formation and development embodies the strong cohesion of China culture itself, and some characteristics and laws of personality formation of folk literature of various nationalities under the inspiration and guidance of this cohesion.
