This is a poem describing the scenery of Qixia Mountain.
The whole poem is as follows:
It used to be the only emperor's house, and the temple never lost its luxury.
If it is not a maple leaf, it is better than a peony flower.
Purple gas does not seek a single cage pavilion, but hongyun sees Qixia.
You can't find steep springs on high mountains. Remember to bring your own tea next time.
