Staircase introduction: The staircase leading to the second floor can be called a smaller version of the Winter Palace. Although the area is not as large as the Winter Palace and other castles, the decoration is equally exquisite and luxurious. The room is breathtakingly magnificent. The halls and pavilions are decorated with white marble columns and pure crystal chandeliers. Many decorations on the ceiling and walls are covered with gold leaf. The level of gorgeousness is impressive.
