Qinhuai Barometer

Lao Zhou has opened a teahouse by the Qinhuai River for thirty years. There is an old painting hanging on the wall. In the painting, the river water changes color with the weather - green on sunny days and gray before rain. Tourists only regard it as a gimmick, but the old neighbors believe it. One day, the painting suddenly turned golden. Lao Zhou was stunned: This is the "sunny day that happens once in a century" that his grandfather said before he died - is it the return of a wanderer, or the rebirth of the old city? He brewed a pot of rain flower tea and waited quietly for the answer.
