Introduction to the Autumn Moon in the Tower Courtyard: At the foot of Wenbi Mountain, there is the Zunsheng Tower Courtyard. Whenever the moon is thin and the moon shadow moves to the west of the Guangming Tower, the Mingyue, Guangming Tower and Zunsheng Tower form a straight line. At that time, the surrounding mountains and forests were hidden in darkness, and only the twin towers under the bright moon showed their majesty.
