How did the opening of the poetry recital lead to Dai Wangshu's Rain Lane?

You can get to the rain lane in the following two ways:

A melancholy love poem/a wandering revolutionary poem/it describes a person's melancholy after being lovelorn/it describes a person's hesitation after failing to realize his ideal/a girl's irreconcilable absence, which inevitably reminds people of Dai Wangshu's Rain Lane.

Rain alley, hazy fog, water drop curtain, reverie under umbrella .../Rain alley, hook's back, hurt tears, heart lane in dream .../Poet Dai Wangshu, please leave us a beautiful reverie forever. Next, let's follow the recitation and enter this sad and beautiful mood.
