Introduction to the front hall: Pass through the upper front room, pass through a low door, and then enter the front hall. The courtyard has tall and tall pines and fish ponds lined up east and west. It is quiet and elegant, giving you a sense of changing scenery with each step. The front hall consists of seven two-story pavilions, and the interior furnishings still maintain their original appearance. There is a copper heater in the middle, which was used for heating at that time.
