Ming Chengzu asked Mr. Feng Shui where he finally chose to set up a platform for rain.

The old minister thinks that this rain platform must be set in the south outside the border, and the south is the sun; Right outside Zhengyangmen Road, left, left is up. "

Judy felt reasonable and said, "According to your words, the empress should beg for rain on the left side of the south gate." This time, Mr. Feng Shui was so busy that they searched everywhere and finally chose a place with a dome. At that time, the round loess pile looked like a piece of gold from a distance and was hard. Mr. Feng Shui said this place is the luckiest in the whole city.
