The grass hall is simple and elegant, with a grand scale and covers an area of more than 300 acres. Among them, the three main memorial buildings of Daxuan, Shishitang and the Ministry of Industry are located on the central axis and are deep and quiet. Between the halls, surrounded by corridors, there is no fun. The flower path in the east, the water sill in the west, the pavilion, platform, pool, and the garden are decorated with a beautiful scenery. There are aromatic forests that cover the sun, plum gardens that are proud of the spring, orchid gardens that are full of fragrance, and green bamboos and pine that are dense like clouds. The whole building is poetic and picturesque, and is a famous garden combining humanistic landscape and natural landscape.
