A poem that begins with seven.

In June, there is no water in the well, and people are tired at night.

Six streets are full of gongs and drums, and the forbidden soldiers hold halberds to guard the empty palace.

Six palaces are silent all their lives, and the silver list shines on the green hills.

The past of the Six Dynasties flows with the water, cold smoke and green grass.

Xian Ye spits on the moon, and a thousand emperors smoke away.

On the seventh day of July, in the Palace of Eternal Life, we secretly told each other in the quiet midnight world.

Seventy-two waiting to quit, Tianguan flew away.

Eight horses went to Wan Li every day, and Mu Wang never came back.

Eight popular pavilions opened a fairy list, and seven scenic spots flew down the stone pass.

The eight-legged cage shook its face and the sun dispersed and dispersed.

Returning in the winter on the 8 th, the five spirits swept the floor and condensed the clouds.

-I hope the answer helps.
