The east wind releases thousands of flowers at night. The stars are like rain. The BMWs and carvings filled the road with fragrance. The phoenix xiao is moving, the jade pot light is turning, and the fish and dragons are dancing all night long.

Moth snow willow gold strands. The first thing you need to do is to get your hands dirty. The first time I saw him, I was looking for him. When I looked back, the man was there, beyond the lights.

Translation:

The east wind whipped by, countless lanterns swaying, as if urging the opening of a thousand trees of flowers, fireworks chaotic, falling down, and as if the stars in the air was blown down, like a shower of stars. Gorgeous carriages and horses came and went on the road, and all kinds of intoxicating aromas filled the street. The sound of Feng Xiao's pleasant music echoed around, and the moon emitted bright fluorescence in the air, its light flowing.

Colorful lanterns in the shape of fish and dragons tumbled in the lively night. The beauties, all wearing bright ornaments on their heads and colorful clothing on their bodies, swayed in the crowd. They wore smiles and passed in front of people with a faint aroma. I searched for her a thousand times, but did not see her, and inadvertently turned around, but saw her standing in the lights scattered.
