Attached to the "Phoenix Seeking Phoenix" one of them:
There is a beautiful person who never forgets to see it.
A day is not seen, and the thoughts are like madness.
The phoenix soars and seeks phoenix from all over the world.
Helpless beauty, not in the East Wall.
Put the piano instead of talking, talk about the heart of the intestines.
When I see Xu Xi, I am comforted.
May the words be worthy of virtue and hand in hand.
Do not fly, and let me perish.

When there is no encounter with Xi, he wu is now xi sheng si tang!
There are beautiful ladies in the boudoir, and the room is full of people poisoning my intestines.
He Yuan crossed his neck for the Mandarin Duck, and Hu Jie soared together!
Huang Xi Huang Xi perched from me, and had to entrust Her tail to be a concubine forever.
Friendship is harmonious, and who knows the middle and night phases?
Both wings flew high, and I didn't feel the afterglow of my thoughts.
