To the north of the Forbidden City in Beijing is the Long Live Mountain and to the south is the Jinshui River, which is exactly in line with the ancient palace building principle of "carrying the yin and embracing the yang, and infusing the qi for harmony".

It was completed in In the early Ming Dynasty, it was located at the former site of Yanchun Pavilion, the palace of the Yuan Dynasty. It was built by excavating the moat and accumulating silt from the South Lake.
