Tanzhe (Pool and Cudrania) Temple is situated 45 km to the west of downtown Beijing. The temple is especially famous for a millennium-old saying; "First there was the Pool and Cudrania Temple, then came Beijing". First built 1,600 years ago in the Jin Dynasty, it was named Temple of Auspicious Fortune (Jiafusi). During the Tang Dynasty, it was expanded and renamed Dragon Spring Temple (Longquansi), Great Longevity Temple (wanshousi) and Mountain Clouds Temple (Xiuyunsi). But, it has been universally known as the Pool and Cudrania Temple because of the lovely Dragon Pool and cudrania trees growing on the hill behind the temple.
