The gatehouse is a symbol that the rich and the poor bring a family. There is a cantilever building at the top of the gatehouse, and there is a double-sided brick carving on the lintel, which is generally engraved with plaques such as "Purple gas comes from the east", "Bamboo, corn and pine". The edge of the barrel frame is decorated with flowers, bats, butterflies and other patterns. The lintel of Lin Mansion, located in the gypsum hall on the street, embodies this feature. Some plaques also show where the ancestors of the house are. For example, Laohe Village in Daqi Street is a A Qing dynasty building named "Flower Wall Gate", and there is a brick carving of "Jianhu Legacy" on the lintel, which shows that the root of He is in Shaoxing. Some big houses put a pair of stone lions or a pair of stone drums on the left and right sides of the gate. Stone lions and drums not only have decorative beauty, but also have the significance of exorcising evil spirits and keeping peace.

There is a significant difference between the archway and the archway: the archway has no "floor" structure, that is, there is no bucket arch and roof, while the archway has a roof, which makes the contrast atmosphere even greater. However, because they are all buildings used for commendation, commemoration, decoration, identification and guidance in ancient China, and they are mostly built in palaces, temples, mausoleums, ancestral temples, offices, and street intersections, and people have not been clear about the concepts of "house" and "building" for a long time, so they finally became interchangeable titles.
