GUIFEI POND (貴妃湯).

My sister who visited China sent me a picture of the Guifei Pond at the Huaqing Hot Springs sent me this picture of the Guifei Pond (貴妃湯). . This is a complex of hot springs located in at the northern foot of Mount Li, one of the three major peaks of the Qin Mountains. It was built in 723 by Emperor Xuanzong of the Tang Dynasty as part of the Huaqing Palace (華清宮), using the locally-occurring geothermal heating.
The Guifei Pond (貴妃湯) is also named Lady Yang's pool.  From the information I gleaned from the Internet, this was where Emperor Xuanzong's Lady Consort Yang Gui Fei had her bath.
