Dongyang Building

　　Dongyang Building is situated to the west of Nanyang Building and was built in the 22nd year of the Jiaqing reign of the Qing Dynasty (1817). It was established by Jiang Zongsi, a grand scholar and grandson of Jiang Shirong, the builder of Er'yi Building. This square-shaped earthen building, located at the foot of Lion-shaped Hill to the south of Er'yi Building, is commonly known as "Lion Cub's Footprint." It faces southeast and is situated northwest, covering an area of 2,200 square meters. The structure has two stories, is 11 meters tall, spans 45.81 meters in width, and extends 26 meters in depth. The entire building slopes from front to back with clearly defined hierarchy. It features an interior corridor-style layout. The main building includes 36 residential rooms and 4 halls. Currently, there are 13 households with 47 residents living here.

　　The gate wall is built from finely polished granite, with a clear hierarchical design sloping from front to back. Two horizontal corridors separate the upper hall, lower hall, and wing rooms. Small doors at both ends of the corridors lead to the kitchen and dining areas. This architectural design effectively minimizes the interference of cooking fumes and steam on the living spaces. The rear hall on the second floor houses ancestral tablets. The rear hall on the first floor serves as a venue for wedding ceremonies. The rooms in Dongyang Building are relatively narrow horizontally, with wing rooms only 2.5 meters wide and the main rooms just 2.8 meters, while depths vary between 5.9 meters and 4.5 meters. The ceiling height reaches 3.8 meters. The architectural design of this building reflects a shift from a primary focus on defense to an emphasis on comfort.

　　In front of Dongyang Building is a courtyard paved with cobblestones, enclosed by a stone wall along the edges. Inside the wall is a well, and outside is a path. A small door opens to the east, and to the south lies a crescent-shaped lotus pond.
