Guangxing Tai Obervatory
China's oldest surviving observatory, Guangxing Tai dates back to the 13th century. It is reputed that astronomers at the time were asked to calculate a calendar year and, even though this occurred over 700 years ago, they were less than 30 seconds different from the accepted modern calculation.
Taishi Shan & Songyang
One of the peaks that make up Song Shan, Taishi Shan's peak is 1494m high and here can be found one of the oldest learning centres in China, the Songyang Academy. The highlight is visiting the two cypress trees located in the academy's courtyard, as they are believed to be over 4000 years old.
