简介：Soon it was evening, and the night was falling. The place where Su Can and the others were sitting happened to face the river. They could see the night view of the river. The lights along the coast were brilliant, tall buildings lined up in rows, thousands of houses were brightly lit, and fish and dragons danced all night long. Brilliant fireworks also rose in dark places, exploding into all kinds of fly ash in the night sky.
