The discovery of three historical materials corresponds to two academic lectures given by Ouyang Yuqian during his trips to Nanjing in 1935.The first lecture,titled"Drama Movement in China"was delivered during Ouyang Yuqian's crucial journey to Nanjing after his return to China in the autumn of 1934.The second lecture,"Directors and Actors"reflects Ouyang Yuqian's interactions with Tian Han and Hong Shen,highlighting the differences in their concepts as directors.Both lectures are intimately connected to Ouyang Yuqian's personal experiences and hold significant importance.Of particular significance is the lecture on"Directors and Actors"which forms an essential part of Ouyang Yuqian's theory on theatre direction.These three historical materials possess not only historical and academic value but also educational value.They have the potential to shed new light on related research and contribute to the exploration of the"School of Chinese Dramatic Performance".Their unveiling opens up avenues for further investigation and understanding in the field.
