Jingshan Park rises from the back of the Forbidden City. It's a fake mountain in this otherwise flat city, built from the leftover dirt from the moats surrounding the Imperial complex. But it's main purpose was to ensure good feng shui. Feng Shui dictates that it's lucky to live on the southern slope of a hill, and all previous imperial palaces had been so placed. Since that wasn't possible in Beijing, a hill had to be built to ensure the imperial family's continued prosperity. The park isn't particularly interesting, although it has a couple Buddhist temples at the top. Also, the last Ming emperor hanged himself here in the seventeenth century, if that makes it more interesting. Doesn't say much about the promises of feng shui though.
