In the winter of the seventh year of the Republic of China, on a cold night in a Shanghai alley, Shen Yanzhi, the concubine of the Green Gang leader Shen Xiaolin, was abandoned on the street by his wife. When he was about to die, Lin Weilan, the general's daughter who had passed through the fetus (with the soul of Lin Wei, a top modern thoracic surgeon, in her body) reached out to help - she took off her woolen cloak to protect him from the cold, and gave him warm snacks to save his life. The dim light that accompanied him for three days became the only salvation for Shen Yanzhi's childhood.
