The back part of the structure is the living area. The whole hall is a typical "waiting room front, living room back" structure. The buildings and houses are all connected by arcades and bridges. Together they form an integrated building with many interconnected passages, something quite rare in the architecture of the time.

Among the seven inner halls, the 170 Song Mao Hall lies at the very center. It is 11-meter wide, 11-meter long and features arcades both at the front and at the back. The front side of the hall is a square. By each side of the hall there are secondary rooms, which are connected with the back rooms through the arcades. The beam columns inside the hall are large and strong, sculptured with depictions of boas, dragons, kylins and other traditional Chinese symbols.

High aloft in the center of the hall hangs a tablet with three golden Chinese characters. These are the "Song Mao Tang" (Song Mao Hall) and were written by Zhang Qian, a leading scholar in the imperial exams at the end of the Qing dynasty (1644-1911). The arcade that faces the main hall is the largest of the five. It is six meters high and covered with upturned eaves. A number of different features, including characters, animals and architecture from traditional Chinese literature are vividly carved around the walls.
