zhang qiang (fang zhongxin) is a myth in the legal world. he has achieved great success in court, but he has been operating a small firm alone for 20 years. K.Cheung&Coaaa。 there are only three people in the company, including him, secretary li shaohua (played by guo shaoyun), and apprentice zhou lixing (played by he guangpei). zhang qiang attaches importance to money and fame and fortune, and meets the largest chinese law firm in hong kong Donald&Co. zhuo jiyao (liu dan decoration), the senior committee chairman, took a fancy to zhang qiang and invited him to join the largest chinese law firm in hong kong founded by him. Donald&Co， liu jinchang (played by liao qizhi); jinchang was a senior executive of the china securities regulatory commission in his early years, with a political and business background and strong connections, and zhuo jiyao gave up Donald&Co. the chairman of the committee made the conditions and strongly invited jinchang to become Donald&Co. managing partner. with the help of his wife wang kailin (played by li biqi), jinchang reached another career peak. later, he found out that jiyao had no intention of giving up, so he cultivated his power in the company, including the sponsor of the delisting case ren weiliang (played by cao yonglian) and transferred to work as a lawyer, and then promoted fang ning (played by huang zhiwen) as a senior partner, intending to force the palace. everything is ready, and the last step of jinchang is to start a large-scale enterprise listing plan to earn the capital to kick off jiyao. however, zhang qiang was actually a stumbling block at this critical moment, disrupting all jinchang's budget. a legal battle that must be fought has become the fuse for jinchang and zhang qiang to be hostile to each other. so, zhang qiang and liu jinchang had a confrontation again and again in the law firm.
