Introduction to the Changyu Centennial Wine Culture Museum: The second floor of the castle is the Changyu Centennial Wine Culture Museum. The moment you enter the museum, you feel as if you have traveled through the long corridor of time and returned to the mottled era a hundred years ago. The privilege of not kneeling in front of Cixi, Mr. Sun Yat-sen's "Taste the Liquan", Mr. Zhang Xueliang's "Gui Dun Yi Miao", each calligraphy and painting, each scene, every light and shadow reveals the flavor of that period of history.
