Lecturer Yu Hui is a researcher working for the Palace Museum, and a member of the National Cultural Relics Appraisal Committee of China. He once served as the director of the Calligraphy and Painting Department of the Palace Museum, mainly engaged in the appraisal and research of ancient calligraphy and painting.

In ancient paintings that fundamentally solve the problem of appraisal, it is possible to uncover the true details of cognitive history and make up for the lack of textual materials. There are two types of such images: first, the author is a witness to a historical event, and their works are authentic or refined original texts by later generations, which is beneficial for directly and vividly understanding the historical events of that time; second, later painters use the real life of that time to depict the events of the previous dynasty, which is also very beneficial for studying the painter's life era. This lecture takes many famous Jidai paintings as examples. Drawing on the principle of textual research, this study attempts to use the method of image research, combined with relevant historical text materials, to identify historical events and objects hidden deeply in the painting, including political, military, and court history information. On the basis of deepening and refining the understanding of auspicious painting content, provide visual basis for further research on ancient history and art history.
