Introduction to the brick-carved gatehouse: The brick-carved gatehouse is located in the northwest of Zhiyukan and is a replica of the Ming Dynasty building. In the middle of the gatehouse, there are three characters "Ji Changyuan" engraved on bricks, and on the back are engraved horses, sheep, tigers and dogs to express loyalty, filial piety and justice. The door is immediately adjacent to the "Qing Xiang" Moon Cave Gate, where small stone lions are laughing and welcoming guests; the rockery is used as a screen in front, through which you can see the real mountain, showing the beauty of the borrowed scenery.
