1. The Nine Dragon Screen at the Palace Museum in Beijing is a remarkable architectural masterpiece that dates back to the Ming Dynasty (1368-1644). The screen stands at over nine meters high and 27 meters long. It was originally built as a partition wall to protect the royal garden from wind and dust. The screen is made up of 635 glazed tiles, each containing a unique and intricate depiction of a dragon. The dragons symbolize power, strength, and good fortune. Interestingly, all the dragons are different in size, expression, and pose, and no two dragons are alike. The Nine Dragon Screen is one of the three surviving screens in China.
