Abstract: Under the academic consensus of integrating moral principles, textual research, and literary artistry during the Qianlong and Jiaqing reigns (QJR) of the Qing Dynasty, scholars also exhibited diverse theoretical orientations. There are three representatives. Firstly, DAI Zheng emphasized textual research over moral principles. Secondly, ZHANG Xuecheng advocated for history as the overarching framework. Thirdly, WENG Fanggang proposed to refine moral principles through textual research, and engage with literary artistry. Recognizing the biases in QJR scholarship, YAO Nai recommended and practiced a unified approach to scholarship. Owing to the approach, literary artistry is enriched with textual research, and moral principles are elucidated through literary artistry. Therefore, YAO demonstrated the feasibility of integrating the three and truly bridged the divides between Han Learning (HL) and Song Learning (SL). He also integrated the historiographical methods of SIMA Qian. By adopting the method, ancient textual research and the spirit of factual recording are highly valued, and more heed is paid to the aesthetic inclination towards the extraordinary, and the literary realm of the strange. YAO had integrated Tongcheng academic view. He mitigated the overly influenced trend of poetry and prose from HL and SL. He also revealed a modern path for the convergence and transformation of the contention between HL and SL, which holds significant academic and literary significances.
