"Past of the Yangtze River" tells the story of the early years of the Republic of China, when the national capitalist industry was initially developing. Xiang Yinweng, who was born into a family of officials, helped his eldest son Xiang Buzheng to start the Xiang family fleet from scratch and achieved success in one fell swoop. Afterwards, the three generations of the Xiang family remained united despite several natural disasters and man-made disasters, and used wisdom and justice to tenaciously protect the Xiang family's Yangtze River Shipping Company to remain standing. This is a legendary business war story.
