Introduction to the Nine Dragon Wall: The Wujin Mountain Nine Dragon Wall is located on the east side of the Crystal Courtyard and is a double-sided Nine Dragon Wall. The Kowloon Wall is 7.5 meters high, 1.5 meters thick and 20 meters long. It is made up of 6574 pieces of specially made colorful glass. Nine flying dragons are distributed evenly and harmoniously on the front. The flying dragons are majestic and fly and dance on the wall. The dragon in the middle is the center of the Kowloon. Its head is forward, its tail is swinging, and its scales are shining and lifelike. The gaps between each dragon are filled with patterns of rocks and water plants, which complement each other and make the picture extremely lively. There are nine dragons inlaid on the back. The dragons of different shapes seem to be rolling among the clouds, and the image is very vivid. The top of the wall is covered with glazed tiles, which are carved with the pattern of two dragons playing with beads. The top is supported by glazed brackets with relief patterns of auspicious clouds. At the bottom of the wall is the Xumizuo. Under the Xumizuo is carved a 1.8-meter pattern of flowing clouds and flowing water, with nine dragon heads inlaid in it. The dragon's head spits clear springs.
