The Phantom of the Opera (then adapted into the movie Musical) written by the famous French detective, suspense novelist and Si Tong Lu Le (1868- 1927) is the glittering building in front of us. As soon as I entered the Opera House, I was immediately attracted by the spectacular grand staircase, in which the marble staircase shone with golden light. It is said that it was polished by aristocratic ladies, so I can imagine the grandeur of the Opera House at that time. There are many fables painted on the grand staircase above the ceiling. If you admire the stairs too much, you may enter the corridor of the Opera House from any side. These corridors provide the audience with social conversation during the intermission. The stairs must be beautiful and spectacular, or Gaynija envisions designing the corridor like a classical castle. The mirrors and glasses under the corridor reflect each other and complement the opera appreciation.
