What do some poems in Wang Changling's Ma Xiaoxu Zhai Hua Zhu mean?

It refers to the wedding night, which means to spend a full moon. In the Tang Dynasty, Luan and Feng were often compared to a couple. Couples were also called bronze mirrors, which meant reunion! Translation:

Peony flower king represents wealth, and purple phoenix is more suitable for bird king.
