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.

There are significant differences between memorial archway and memorial archway:

The archway has no "building" structure, that is, there is no bucket arch and roof, while the archway has a roof, which makes the contrast atmosphere even greater.
