Introduction to the Yingxun Gate Tower: There are six ancient city gates in Pingyao, two on the east and west sides. A bird's-eye view of the ancient city of Pingyao looks like a tortoise about to move. The "tortoise" has its head south and its tail north. The four east and west gates are likened to the four legs of a tortoise. Therefore, it is known as the "Turtle City" among the people. Outside the south gate, the Zhongdu River meandered by in ancient times, which inspired the ancient literati to lament that "playing in the water in front of the turtle, the mountains and rivers facing the sun, the city was built with this in mind". The turtle is a symbol of good luck and longevity. The term "turtle city" originated from the ancients' worship of the "four spirits". The "turtle city" means solid gold soup and long-term peace and stability.
