As a new chapter in the "Big River" series, "Difficult Manufacturing" has always been called "Big River 4" by fans, and it has been highly anticipated by netizens since the beginning of filming, especially after the end of "Big River 3", everyone's attention to period dramas has skyrocketed. 
Although the tax problems of the heroine Song Zuer have affected the prospects of the series, it was even hopeless to be launched for a while. But with the hope of Song Zuer getting out of the whole body, and the strong support of the broadcast platform, "Difficult Manufacturing" now has a time to be launched in March, which can be described as a very pleasant surprise! 
In the context of a later era, "Difficult Manufacturing" not only opens a new character system in the plot, but also adds more powerful factions to the original "Iron Triangle" configuration, which can be described as a comprehensive upgrade of the lineup, and the wonderful plot is also in a state of doubling the output! 
First of all, "Difficult Manufacturing" is directed by Li Xue, and the whole drama is actually based on Liu Jun, the male protagonist who returned from studying abroad, how to transform the old machinery factory into a modern manufacturing plant with leading technology through his own efforts, telling the story of the take-off step by step in the late 90s, when private enterprises were constrained in all aspects, with continuous learning and progress. 
Compared with the first three series of "Big River", the story timeline of "Difficult Manufacturing" is closer to us, and the characters and stories selected are also more in line with the background of the times. not only focuses more on entrepreneurship, technological innovation, business and other elements, but also with the return of "old characters" such as Song Yunhui, Yang Xun, and Liang Sishen, the highlights of the whole drama are also very sufficient. 
Moreover, in terms of the lineup, the male advocate of "Difficult Manufacturing" is undoubtedly the best among the new generation of actors, not only with outstanding appearance, but also with very solid and skillful acting skills! can get the favor of the noon sun many times, and Zhang Xincheng will also usher in a new chapter. 
Then there is the heroine Song Zuer, aside from the off-site controversy, returning to the works and roles, Song Zuer's strength in all aspects is still the best among the 95 flowers in the same period! With sweet and atmospheric appearance, explosive acting skills, and rich experience in period drama performances, the performance in "Difficult Manufacturing" is still very worth looking forward to. 
In the rest of the lineup, Wang Yanlin, who plays the second male lead, Zhang Yue, who plays the second female lead, and supporting roles such as Liu Yitie, Wang Yinglu, Zhu Yuchen and Liu Yijun, are also actors we are very familiar with and love. Each of them has very strong acting skills, and in the past works, they have all had very bright performances, which can also bring stronger competitiveness to the series. 
In addition, because there are many linkages with the "Dajiang Dahe" series, and even some or very important roles, Wang Kai, Yang Shuo, Yang Xun, Yang Caiyu, Lian Lian and other leading actors in "Dajiang Dahe 3" will also appear in "Difficult Manufacturing". Among them, Wang Kai and Yang Xun will have a lot of rivalry with Zhang Xincheng, which undoubtedly improves the strength and competitiveness of the drama to a certain extent, and also allows the audience to substitute into the story script at the first time. 
With the past production level of Noon Sunshine, and the reputation and popularity of the "Big River" series, "Difficult Manufacturing", which has a strong lineup and excellent production in itself, obviously has a very good prospect for broadcasting! Although the Song Zuer incident is still a major "hidden danger", I believe that with the wonderful plot and brilliant characters, "Difficult Manufacturing" is still expected to become the new king bomb in period dramas.
