Introduction to the Xuanjianlou Stage: It is now the gate of the Folk Museum. It is said to be the largest existing ancient theater in Henan. It is a two-story, double-eaves, mountain-style building with five rooms in width and three rooms in depth. When it was originally built and designed, the perspective of the audience below the stage was fully taken into consideration, so that the performance on the stage could be seen clearly from different angles.
