What does this poem mean! Accustomed to Xin Qing dance, Yan Luan is suspicious.

Poet: Zhao Shankuo Dynasty: The first altar in the Song Dynasty held the sky low in order to humble worship Yunxia. Accustomed to Xin Qing dance, Yan Luan is suspicious. The sound of stepping on the air is still ringing, and the precious seal is not exposed. Star embroidery is eternal, and it is suspected that Yao Men is in danger. The momentum of the altar seems to be under the blue sky, just like peeping at the stars in the clouds. The cranes in the forest are used to dancing when they hear the sound of metal impact, but the phoenix bird unconsciously flies to the altar. The sound of walking resounded through the sky, and after writing beautiful words, the sandalwood was finished and the dew was still wet. The stars in the sky decorate the long night, just like driving in the wind and knocking on the door of jade ornaments.
