In the three-act drama Teahouse, there are more than 70 characters, 50 of whom have names or nicknames. The identities of these characters vary greatly. Some of them were members of parliament, some were directors of the gendarmerie headquarters, some were left over from the Qing Dynasty, some were leaders of local evil forces, some were storytellers, fortune tellers and peasant women, and so on. All kinds of characters constitute a complete "social" level.

Teahouse shows the characteristics and culture of the teahouse in each specific historical period through the change of the furnishings of Yutai Teahouse from simple to new and then to simple. At the beginning, tea drinkers played with birds, tea and insects. Although they were antique, they were all quiet because of the appearance of "detectives" and the note "Don't talk about state affairs".

The survival of the "Yutai" in the second act, the renovation of teahouse facilities and the contraction of the scene imply the teahouse's struggle in this increasingly contradictory society. The bigger the "foreign flavor" in the teahouse and the note "Don't talk about state affairs" written by Zhang Yue, the greater the crisis.

In the third act, not only did you write a note "Don't talk about state affairs" with a large number, but there was also a note next to it: "Pay for tea in advance". This shows that the teahouse has reached the point where it can't make ends meet. "Pay for tea first ... don't talk about state affairs" obviously embodies a causal relationship. Lao She takes the teahouse as the carrier, sees the big from the small, and reflects social changes.
