In the 23rd year of the Republic of China, war was raging, war broke out in the south of the Yangtze River, and the Su family was in decline. Su Wanqing went to Shanghai alone to make a living, and traveled around ten miles to survive. During a reconciliation at a foreign bank, she unexpectedly met the calm Lu Yanci. There were many misunderstandings when they first met. Lu Yanci recognized her as the daughter of an old friend whom he had longed for when he was young, and protected her silently and secretly, protecting her from the harassment of gangsters and the schemes of her peers.
In troubled times, the current situation is turbulent, the Japanese army covets Shanghai's commercial port, Lu Yanci's industry is in crisis, and Su Wanqing spends all his savings to help. The luxuriant concession hides the dilemma of family and country, and the love between children is wrapped up in the broken mountains and rivers. The two stayed together amidst gunfire and rumors, abandoning their stability and wealth to protect the refugees with their meager efforts. An old letter tied them together for half a lifetime. In the flames of war, they held on to their tender tenderness, waiting for the mountains and rivers to settle down, and staying together year after year.
