円明園
Tsinghua Garden, originally the Xichun Garden, was granted as a gift by the Kangxi Emperor to his third son, Yinzhi (Prince Cheng). It was part of the Old Summer Palace and was called the "East Garden" (東園) because it was located to the east of the Old Summer Palace. The Kangxi Emperor visited the garden ten times when the garden was owned by Yinzhi, and celebrated eight of his birthdays at the garden, including his 60th birthday in 1713. He also wrote calligraphy for five plaques displayed all over the garden, one of which was the garden's name (Xichun Garden).
