In the misty rain in the south of the Yangtze River, Su Wanqing guarded an old bookstore with green lanterns, waiting for twenty years. When we saw each other off at the ferry, the young general Shen Yanci promised to come back and stay with him after the border was settled.

After twenty years of wind and frost, the old man, covered in dust and with hoarfrost on his temples, opened the door of the shop. A belated call finally gave the long wait a home. A green lamp no longer shined alone.
