There is a word about Yang Guifei's "as if". One sentence ends with Yue and the next begins with Qi. I saw it in my knowledge before, but I can't find it later.

Qing ping Diao yi

Clouds need clothes, flowers and capacity,

The spring breeze opened the threshold and showed its richness.

If it weren't for the head of the Yushan Mountains,

I will meet Yaotai under the moon.

Clear and flat tone, second.

Red dew is fragrant,

Making love is a waste of time.

Excuse me, who looks like Han Palace?

The poor swallow leans against her new makeup.

Qingpingtiaosan

Famous flowers poured into the countryside and enjoyed each other.

The king always smiles.

Explain the infinite hatred for the spring breeze,

The agarwood pavilion leans against the pole in the north.
