Introduction to the Four Dragon Walls: The Four Dragon Walls are located directly south of the end gate of the Guandi Ancestral Temple. They are glazed screen walls fired during the Xuande period of the Ming Dynasty. The picture is divided into three realms: heaven, earth and sea from top to bottom. The main body is four dragons flying around, set off by phoenix, unicorn, jade rabbit and other auspicious birds and beasts, giving this four-dragon wall many traditional cultural connotations.
