Undoubtedly as the treasure for Chinese classical gardens, Summer Palace was built in the 41st year during Emperor Kangxi's reign (1702). The Summer Palace is constituted by four parts, namely, imperial palaces, the front area of Longevity Hill, the back area of Longevity Hill, and Kunming Lake Area. It not only boasts a sophisticated overall design but also houses exquisitely designed buildings and landscape, demonstrating China's highest level of gardening art.
