October 25, 2025, noon, light rain. Liaocheng Ancient City is essentially a city within a lake, surrounded by Dongchang Lake. Guangyue Tower, located at the very center of the ancient city, is massive in scale and overlooks the entire city, perhaps holding significant military importance in ancient times. The lake's water system is connected to the Grand Canal, and Liaocheng is a city that flourished because of the Grand Canal—in a sense, it even belongs to the Grand Canal itself. Modeled as a single entity.
