Who wrote the preface to The Book of Songs Nan Zhou Guanju?

The Book of Songs is out of order, and the order proposed here should be Mao's order. The following is quoted from Baidu Encyclopedia: "Preface to Mao Poetry" has a so-called big preface and small preface. The small preface refers to the solution of 305 articles in Shi Mao handed down from the early Han Dynasty, and the big preface is the preface of The Book of Songs after the solution of the first article "Nan Zhou Guanju". The preface to Mao Shi mentioned here refers to a grand preface. As for when and by whom the Preface to Shi Mao was written, it has been a controversial case since the Han Dynasty, and it has not been satisfactorily resolved so far. According to Hanshu Yiwenzhi, there are 29 volumes of Shi Mao and 30 volumes of Biography of Shi Mao, while Ban Gu only said that Han Xing and Lu were exegesis of the poem, and Qi Yuangu and Yan Hansheng were biographies. ..... and Mao Gong's theory, which is called Xia Chuan, and the river offers a good king ... In The Scholars, it still only says: Mao Gong, Zhao Ren. Doctor Mao's name is not recorded in The Book of Songs, and Wang Dafu is not recorded in Hejian. Later, Wu went from Zheng Xuan to the Three Kingdoms, and it was reported in succession that Mao Heng of Lu was Mao Gong and Mao Ji of Zhao was Xiao Mao Gong, both of whom were in charge of poetry in the early Han Dynasty. As for Preface to Poetry, there is a passage by Xia Zi, a disciple of Confucius. It was not until the Qing dynasty that everyone held their own words and argued endlessly. The General Catalogue of Sikuquanshu synthesizes all the expositions, and holds that the first two words of the Preface, namely, the small preface of Guanluojie, were handed down by the former teacher of maoji. The big preface after the small preface was attached by the disciples below the clam. This view is generally close. That is to say, The Preface to Mao's Poems summarizes the theoretical opinions of Confucianism on the Book of Songs since the pre-Qin period, which was further developed by Mao's collection of Zhao people during the reign of Emperor Jing of Han Dynasty, forming an article, and then revised and improved by his disciples.
