Qiyuan, located in Dongshan along the coast line of Taihu, is also named as Xijia Garden. It was built for his ancestor had waited for the arrival of Kangxi Emperor in this location. It is the only garden built closely to the mountain and river in Suzhou. The whole garden is surrounded by four-side halls, Galleries, lakes, rockeries, and the new buildings, echoing a harmonious and balanced composition. Especially "Royal dock" in the garden, embedded in the Taihu Lake, is very poetic.
The main buildings of the garden are four-side halls, among which “Jinghu hall" is the most spectacular one. Surrounded by hills and tress, Jinghu hall is four-side and two-story, dignified and elegant. There are real bamboos but fake bamboo shoots, and the ground paved with small stones, and flowers, such as peony, camellia, osmanthus, Hongfeng, and Lamei. The ancient waxberry tree, the ancient Liu Yi well and the Royal dock from where Emperor Kangxi went to Dongshan, are known as three treasures of Qiyuan.
