《四世同堂》和《茶馆》在创作思维和艺术形式上均有沟通之处，这种沟通主要体现为小说和戏剧在人物的塑造技法的相互引鉴，在结构艺术上的相互渗透以及在第一部和第一幕上的相互映照上。这种沟通与老舍具有的深厚的生活底蕴、文化思想和小说、戏剧艺术修养有密切的关系。 Both “Four Generations” and “Teahouse” have their own way of communicating with each other in terms of creative thinking and artistic form. Such communication is mainly manifested in the interaction between novels and the dramas in shaping the characters, mutual infiltration in structural arts, and In the first and the first act of mutual reflection on the screen. This kind of communication is closely related to the deep life, cultural thoughts and novels, drama and art cultivation that Lao She has.
