We came too early . There're still three hours before the performance starts .   I know . Sorry , I shouldn't have rushed you , but I just couldn't stay at home and wait .   Never mind . What about taking a look around the theater ?   Why not ? I'd love to do that .   Here we go . There is a museum of the Beijing Opera art . ( They come to the museum of the Beijing Opera art . )   Wow . Look at this . So delicate and beautiful . Did ancient Chinese people really wear them ?
