Yong Sang (Cai Zhennan) is the boss of Jianguo Market. He is wise, brave, and highly respected. He is deeply respected and loved by his younger brothers. All matters in the market are presided over by Yong Sang. Qing Feng (Sun Peng) is Yong Sang's most trusted subordinate. Although it is not made clear, everyone knows that Qing Feng will take over his position after Yong Sang retires. Ah Xiong (Huang Hongsheng), who was imprisoned for three years for murder, returned to Yong Sang after being released from prison. In fact, he did not commit a crime, but took the blame for Qing Feng. Yong Sang values Ah Xiong's ability very much and even decides to hand over the Jianguo Market to him for management. However, Ah Xiong has already decided to quit. He does not want to repeat the same mistakes and just wants to be a clean person and live a quiet and peaceful life. Michael (Wang Yangming) returned from studying abroad and was determined to change the corner system that has been practiced in the market for many years. He put the first goal of reform on Yong Sang.
