Looking for a new identity as a woman and a worker; Lin Huai came from the countryside and joined the army based on his ability, and was used to the warlords' competition and the warmth of people's hearts; and Aqiu, who grew up on the river, relied on coolies to earn a living, and had many ups and downs, and fought openly and secretly. Everyone has his own way, and each road has its own winds and rains. Ancestral halls, teahouses, newspapers, cotton mills, docks, platforms, the rails run over the bluestone, and the whistle strips away the dream of the town.
