Introduction to the gate of the Cao Family Old House: The Cao Family Old House is located in Shaluo Village, Daxi Township. The old house was built in the Qing Dynasty and is an Anhui-style building. At the main entrance of the old house, there is an earth wall about 30 meters long. The left and right ends of the top of the wall resemble the tail of a phoenix, which is very beautiful. The door frame is inlaid with strip stones, and there are brown patterns on the door forehead. Climb the five stone steps and step through the gate, and you will arrive at the Sihe Patio. The ground here is paved with stone slabs. From the patio, you can walk up the four stone steps to the main hall. The ancient stone jar on the right is designed for fire protection. The stone holes in the noodle stone can play a role in drainage, which is reasonable and scientific.
