Is “In the History of Song, there is a contradiction in the records of who impeached Feng Jing in the Zheng Xia case: The biography of Zhang Zao records that Zhang Zao impeached Feng Jing to flatter Lü Huiqing; while the biography of Lü Huiqing records that Lü Huiqing instigated the censor Zhang Hu to impeach Feng Jing.” true?

In the History of Song, in the collective biography 'Li Qingchen, An Tao, Zhang Zao, Pu Zongmeng, Huang Lü, Cai Ting, Wang Shao, Hou Cai, Xue Xiang, Chang Yan, Zhang Jie', the biography of Zhang Zao records: 'When the Zheng Xia affair arose, Zhang Zao, to flatter Lü Huiqing, impeached Feng Jing for having connections with Zheng Xia, and with exaggerated words, brought Feng Jing and others to guilt.' That is, it indicates that Zhang Zao impeached Feng Jing. However, in the History of Song, in the first chapter of the 'Biographies of Treacherous Officials', the biography of Lü Huiqing, when recounting the same event, states: 'Lü Huiqing exposed the matter, and also instigated the censor Zhang Hu to jointly impeach Feng Jing as a partisan.' The two accounts contradict each other regarding whether it was Zhang Zao or Zhang Hu who came forward to impeach Feng Jing, leading to his conviction. This is clearly a discrepancy in historical facts resulting from failure to unify during the compilation of historical materials.
