Kunming Lake
The design of the Summer Palace was based on a legend in Chinese mythology about three divine mountains in the East Sea, namely Penglai, Fangzhang () and Yingzhou (). The three islands in Kunming Lake – Nanhu Island (), Tuancheng Island () and Zaojiantang Island () – were built to represent the three mountains, while the lake itself was based on a blueprint of the West Lake in Hangzhou. Besides, many architectural features in the palace were also built to resemble or imitate various attractions around China. For example: the Phoenix Pier () represented Lake Tai; the Jingming Tower () resembled Yueyang Tower, Hunan; the Wangchan Pavilion () resembled Yellow Crane Tower; the shopping streets were designed to imitate those in Suzhou and Yangzhou. The centrepiece of the Summer Palace was the "Great Temple of Gratitude and Longevity" (). There was also a Long Corridor more than long which was furnished with artistic decorations. As the palace was not equipped with facilities for long-term staying and daily administration of state affairs, the Qianlong Emperor hardly lived there and only remained there for the day whenever he visited it.
