Understanding of "Cold" in "Cold Water in a Smoke Cage" in Bo Qinhuai

Cold refers to the cold weather, but also refers to the heroine's inner loneliness and sadness.

Translation:

Autumn waters are rippling on the Qinhuai River, and twilight is dancing like a veil.

Autumn water is full of charming smoke, and the beaches on both sides of the river sink into the dissolved moonlight with the night.

I watched quietly on the moored boat, and the lights of the restaurant on the other side were brilliant.

Singing girls are like spring, "tourists" are crazy, and the song of "backyard flowers" permeates the north and south of the river, but who would have thought that the country would be destroyed?
