The dramatic structure of Teahouse is very unique, and it is called "Tujuan Opera". There are no complete plot clues and conflicts throughout the work, but the activities of many characters drive the development of the plot. Cao Yu's Thunderstorm and Lao She's Teahouse are both close to the social era, and they are both dramatic forms, but their structural characteristics are completely different. Thunderstorm adopts a compact and concentrated drama structure, and the author skillfully uses the methods of "review" and "interlude" to interweave "the present drama" and "the past drama", which fully shows that the contradiction between Zhou and Lu is sharp and concentrated, and the plot develops fiercely.

There are more than 30 characters in the second act of Teahouse, and nearly 20 people have lines, but these characters have no obvious distinction between primary and secondary, and everyone has few lines. They passed each other in the teahouse and talked about their own affairs. The activities of the characters in the play are all about intercepting a cross section of them in the teahouse. These countless pictures are organized to form a scroll painting, which gradually unfolds with the plot. Cao Yu's Thunderstorm has few characters, but the relationship is complicated. There are masters, times, and characters' language actions all revolve around the same contradiction. For more than 30 years, the contradiction between Zhou and Lu has been great.
