Yuanmingyuan （Old Summer Palace）, known in China as the Gardens of Perfect Brightness, was a complex of palaces and gardens, built in the 18th and early 19th century, where the emperors of the Qing Dynasty resided and handled government affairs (the Forbidden City was used only for formal ceremonies).
Yuanmingyuan（Old Summer Palace） is an historical park in Beijing. Even though it has been left in ruins from the destruction from foreigners more than 150 years ago, it is still a popular park where many locals enjoy trails, lakes, and can learn the history of the ruins that are all throughout the park. The guiding principle for the park’s development is to transform the lakes and streams and plant trees on a large scale, while accentuating the importance of the historical ruins as a prominent feature of Yuanmingyuan.
When you walk and look around this park，you can found there are many places where it would be good to hide a cache, but this is a special place because there is a saying in Chinese ：the most dangerous place also is the safest place.
At autumn，the Yuanmingyuan（Old Summer Palace） is very beautiful。Ginkgo biloba leaves and maple leaves begin to turn yellow and red, the lotus has withered and workers are also starting to prepare the winter for the plant。
