In the thirteenth year of Chunxi's reign, Lin'an Cao merchant Shen Huaijin drowned in the canal. The government said it was a drunken incident. His son Shen Duzhou didn't believe it - his father never drank. Starting from three broken boats, we go all the way north along the canal: visiting old friends in Suzhou, meeting a strange woman in Yangzhou, seeing the smoke on the front line in Chuzhou, and revealing a shocking secret in Xiangyang. A river runs from north to south, recording the ups and downs of three generations. This is a road that a Cao merchant boy walked from the market to his home country in the sound of oars and lights on the canal.
