In 1936, in order to save her younger brother, Chen Hedi, a daughter of the Zhujiang Dan family, signed an incomprehensible deed and sold herself to Shamian Foreign Company. There, she met Shen Weihan, a scholar whose brother had paid off his debt. There is an illiterate person who knows all kinds of water conditions on the river, and a man who is full of poems and books but cannot understand people's hearts. He gave her a jade bracelet and said he would marry you when I come back. The war came, he left, and she waited. Half a jade bracelet, two lovesicknesses. The trees on the sand are still there, and the moon on the river is still full, but I don't know if the people who are waiting will come back.
