. The plot of Midnight is embedded in the real historical time and space from May to July of 1930. It reflects the contradiction and struggle between Wu Sunfu, a national industrial capitalist, and Zhao, a comprador financial capitalist, vividly and profoundly reflecting the social outlook at that time. At first, Zhao harassed Wu Sunfu to speculate in public debt, and Wu Sunfu joined other capitalists to set up trust companies, trying to vigorously develop national industries, thus creating contradictions with Zhao. With foreign financial capital as the background, Chair Zhao opposed Wu Sunfu everywhere. In addition, warlords scuffled, the countryside went bankrupt and factory workers went on strike. Although Wu Sunfu and his accomplices tried their best and struggled desperately, they did not change the fate of complete failure. This tragedy shows that under the aggression, control and oppression of imperialism, China's national industry will never develop. Although people's livelihood was depressed and wars continued in China in 1930s, it was a different scene in urbanized Shanghai. Here, there are people who are drunk and dream of death, intrigue and intrigue, and all kinds of people who agree. Wu Sunfu, the father of a silk factory in the countryside, fled the war and came to Shanghai. The confusing urban landscape made the old man who stayed at home deeply stimulated and suddenly died. Wu Fu held a funeral, and all the dignitaries in Shanghai came to offer their condolences. They gathered in the living room to inquire about the war, talk business and socialize. Zhao, a comprador capitalist who is good at speculation, found Wu Sunfu and his brother-in-law Du Zhuzhai and wooed them to form a huge public debt "bull stock", hoping to buy cheap and sell expensive in stock trading and reap huge profits from it. Tu Chu-chai hesitated, so Zhao revealed to him his plan to manipulate the war with money. Wu and Du decided to follow Zhao. This cooperation, with a small wave, finally succeeded. Because the confusion and speculation of financial bonds hindered the development of the industry, colleagues Sun Jiren and Wang recommended Wu Sunfu to unite powerful people from all walks of life to set up banks as their own financial circulation institutions, hoping to use most of their own capital to run several transportation, mining and other enterprises in the future. This is exactly what Wu Sunfu wants. He is ambitious and adventurous. He likes to work with people as far-sighted as himself, but he has no mercy on those half-dead capitalists. Soon, Zhong Yi Trust Company was established. At this time, Shuangqiao Town, Wu Sunfu's hometown, changed, and farmers rebelled, causing losses to some rural industries. Frequent labor disputes in the factory also made him fidgety. In order to deal with the workers' strike, Wu Sunfu used Tu Yuewei, a brave and scheming young clerk. One is to secretly buy off Yao Jinfeng, the head of the female worker, and disintegrate the labor movement organization. After the incident, Yao Jinfeng was regarded as a capitalist's running dog by the workers. When the labor unrest resumed, he falsely ordered Wu Sunfu to dismiss Yao and promoted the storyteller. In this way, Yao's prestige was restored, but the workers refused to accept her disposal. So, as a concession, Wu withdrew the order not to expel Yao and comforted the women workers to give them a day off. Wu Sun-fu complied, and the strike really subsided. The struggle of the exchange is becoming more and more fierce. The original alliance between Wu Sunfu and Zhao turned into a situation of confrontation and struggle. As a force to contend with Zhao, trust companies have formed a struggle between Zhao as a "cow" and the company as a "bear". Zhao took a fancy to Wu Sunfu's fat, and when he was short of money, he wanted to swallow Wu's property. After several rounds of competition, Zhong Yi lost 80,000 yuan and stumbled to a halt. At this time, Wu Sunfu's funds became increasingly tight, and he began to exploit workers' labor and deduct wages. With the arrival of a new round of strikes, Tu's introverted tactics of disintegrating workers' organizations were discovered, and Wu Sunfu was caught in a dilemma of internal and external pressure. Zhao wants to invest in Wu Sunfu's bank. Wu is determined to fight for it. He even mortgaged his silk factory and mansion to make public debt, with the last resistance as capital. He finally knew how difficult it was to develop national industry in China. Concerns about personal interests made him involuntarily involved in the speculative market of short selling. The public debt situation was critical, and Zhao manipulated the management of the exchange, embarrassing short seller Wu Sunfu. Almost desperate, Wu Sunfu pinned his last hope on Tu Chu-chai. At this critical moment, Du defected to Zhao's side. Wu Sunfu is completely bankrupt.
