Song Yun Hui --- Wang Kai
Song Yunhui was transferred to the Pengyang Pesticide Factory as the factory director, which couldn't compare to Donghai in various aspects. As a newcomer to the field of pesticides, Song Yunhui experienced a huge gap between Donghai and Pengyang. However, his pursuit of truth and his determination to strive never wavered. Despite facing the pressure of others' skepticism and even paying a painful price, he persevered in leading the Pengyang Factory's research and development efforts. Through his unwavering dedication, he revitalized the small pesticide factory on the brink of being shut down.
Lei Dong Bao --- Yang Shuo
Lei Dongbao led the Dengfeng Wire Factory to merge with small factories, forming the Thunder Cable Cluster. He established rules, participated in bidding, engaged in foreign trade, and attracted investment. He experienced the ups and downs of human relationships while expanding his business. However, the situation where everyone responded to his call no longer existed.
Yang Xun --- Dong Zi Jian
Yang Xun partnered with Liang Sishen to build a shopping mall, leveraging the Liang family's connections. In the shady business world, he couldn't escape from being manipulated. He often found himself torn between being a good person or a bad person, but ultimately struggled to do what gives him peace of mind.
Liang Si Shen --- Yang Cai Yu
Liang Sishen made every effort to balance the interests of both parties in the construction of the Donghai-Luoda joint venture factory. She persisted in breaking stereotypes in her own way and gained the trust of the technical staff. However, she consistently faced exclusion and difficulties from her colleagues at Luoda. The investment in the shopping mall built for Yang Xun took an unexpected turn.
