In Shanghai in 1930, Wei Ruolai, as an ordinary employee of the Kuomintang Central Bank, gradually gained the appreciation of senior consultant Shen Tunan with his outstanding work ability. In the process, Wei Ruolai saw many corruptions and darkness in the financial field of the Kuomintang. In the confusion and depression, Communist Party member Shen Jinzhen used Marxism as a guiding light to illuminate Wei Ruolai's heart. Different choices made him and Shen Tunan part ways in the end. Under the arrangement of the organization, Wei Ruolai and Shen Jinzhen moved from Shanghai to Jiangxi. Under the strong leadership of the party, Wei Ruolai participated in the war without gunpowder to smash the Kuomintang's economic blockade of the Central Soviet Area, and gradually grew into a red financier who could stand on his own on the economic front of our party.
