Suzhou is China s well-known city of gardens，which tops all other cities in both the number and the artistry of gardens. Suzhou's art of gardening has undergone a history of 1,500 years. The Ming and Qing Dynasties between the 14th and 20th century were its prime periods of garden building. At one time there were more than 200 private gardens in the city. A lot of them are still preserved in good condition today. The unique charm of these gardens has led to their entry into the list of World Cultural Heritage in 1997.
