Introduction to Rainbow Post: Rainbow Post is located on the west bank of Peach Blossom Pond, south of Leiyu Dun, and separated from Leiyu Dun by a small stream. Every time it starts to rain, a rainbow will appear across the hilltop and the cliff will glow, hence the name "Rainbow Hill". There are cliffs everywhere near the water. The cliff pattern looks like the skin of a tiger and the skin of a dragon, which is really rare. There is a rainbow bridge on the stream connecting it with Leiyu Pier.
