In the twenty-seventh year of the Republic of China, Shen Zhiyi, the daughter of a well-known Suzhou engraving family, came to Shanghai with a locked box. What was in the box was not gold or silver, but a set of knives and a list of revolutionary patriots since 1911. She didn't find the person her father entrusted to her, but she met Lu Shaochuan, the young master of the Lu family in Zhabei at the intersection of Xiafei on a rainy night - a man who had risen from the blood and fire and hid his father's boat in the Suzhou Bay for seven years.
From the French Concession to the Hongkou Warehouse, from the hand carving the copper plate to the hand holding the gun, the two people walked side by side in the undercurrent of Shanghai. The Japanese wanted the roster, the Qing Gang wanted the docks, and Chongqing wanted the map. And the carving knife in her hand has carved rifling, carved waterways, and carved the loquat flowers that her mother has not finished carving. He said I will protect your life, and she said the loquat is ripe, let's eat together. In troubled times, two people can go as far as a carving knife can carve.
