Chen Jianghe (Zhang Yi) is an orphan who was picked up and brought up by Chen Jinshui (Tao Zeru). He was gifted in business since he was a child and learned how to quickly value and exchange goods by exchanging chicken feathers for sugar. In the 1980s, the Yiwu small commodity market was booming. Chen Jianghe traveled all over China and had the qualities of a successful businessman. He met Luo Yuzhu (Yin Tao) and Yang Xue (Gao Shuyao), who had returned from studying abroad, and started a love-hate relationship with these two women for more than half a century. In the 1990s, the Yiwu market was booming. Chen Jianghe and Luo Yuzhu became the leaders of the mall, but Yang Xue, who hated love, became Chen Jianghe's biggest business competitor. Yang Xue restrained Chen Jianghe everywhere and vowed to tangle with him to the end. Chen Jianghe pondered over the way out and resolutely made up his mind to reconcile with his opponent and face the outside world in unison. As the interests of the two people became entangled, Yang Xue began to think about the value and significance of her fight with Chen Jianghe, and finally married Ruan Wenxiong (played by Zhang Zhaohui), a generation of business tycoons. In the new century, China's Internet e-commerce has developed by leaps and bounds. Chen Jianghe and Luo Yuzhu's son Wang Xu (played by Hua Kun) slowly took over the family business. Wang Xu was born to Luo Yuzhu and her first husband. He was a melancholy and taciturn boy since he was a child. In addition to his family, the only one who was with him was his childhood sweetheart Qiu Yan (played by Zhang Jianing). Qiu Yan went abroad to study, and Wang Xu stayed in China alone to fight. In the collision of new and old ideas between the two generations, Wang Xu gradually matured and broke out a road in the crisis-ridden business environment. Wang Xu's generation of young people has a keen observation. When he saw the national strategy of the Belt and Road Initiative, Wang Xu realized his father's foresight and also found a new direction to plug the wings of the Internet into traditional business. This is not only a way out for the group, but also a way out for the entire Yiwu! Little did they know that Ruan Wenxiong, a lone wolf in the business world, had already set his sights on Wang Xu, and was ready to use the capital market to plunder the fruits of Wang Xu's hard work. Rumors were spreading in the business world, and the group's stock price was up and down. In the midst of the storm, Qiu Yan returned from abroad, and the two young people who had a rough relationship joined hands to fight like their parents did back then. In times of crisis, Chen Jianghe and Luo Yuzhu, who had retired to the countryside for a long time, came out to help their son, and through the combination of the wisdom of two generations, they overcame the crisis and turned enemies into friends with their business rivals. The old Yiwu people have inherited the tradition of opening four doors and six doors, and the family finally reunited after experiencing ups and downs...
