In the 1921s, the Mu family was composed of five big families, which were all famous families in Shandong and even the whole country. Moujin, the head of the family's young generation, was suddenly dying, and several uncles of Moujin were eyeing up to take his place. Jiang Zhenduo, a wealthy family, had to suppress his grief and deal with the second, fourth and fifth masters who fought over the head of the family. In particular, as a second-class official and president of Qixia County Chamber of Commerce, the second uncle Mou Zongsheng is determined to win, and he will fight for the position of head by any means. The beautiful and clever young housewife endured the grief of losing her lover. For the sake of family prosperity, she resolutely met the challenge. With the help and support of her mother-in-law, Lu (the first wife), she wooed the malicious fourth grandfather Mou Zonghao. The election ceremony was held in the ancestral temple. The first wife proposed that the daughter-in-law Jiang Zhenguo would compete for the head of the new church on behalf of the new church, and convinced all the lords with various facts. Yuexintang, Sir Zhong's home, has long been in weddings, and the wives of all rooms have been buttering up their second wives. Yuexintang has killed chickens and slaughtered sheep, and everything is ready except the east wind. Ancestral temple, according to the rules set by grandpa four, is elected by secret ballot. Red beans and mung beans represent the first wife and the second master respectively. In the first round, the red beans and mung beans were flat, and a pea came out! Grandpa four mobilized to vote again, but the result was that Jiang Zhenduo won by a narrow margin. Jiang Zhenduo finally became the head of the family and took charge of the family portal. However, how to deal with the intrigue within the family and inherit the family business of Guangda Mou has become the first difficult problem to test the wealthy family.

At the same time, a scholar came into Jiang Zhenduo's life. His surname is Wang, and he once participated in the patriotic student movement. He has advanced ideas and full of ambitions. Because he escaped from hunting and returned to his hometown, Grandpa Four, who was drunk late at night, met Mr. Wang and gave birth to another fate. Mr. Wang made a living by teaching for the time being. The eldest wife appreciated Grandpa Four's support for Jiang Zhendong and asked Grandpa Four to find a new private school for the children who neglected their studies in the manor (Mr. Yuan was resigned because of a fight between Mou Chang and Yan Kun). Grandpa Four remembered Mr. Wang and decided to invite this handsome gentleman as a chess piece placed beside the young widow Jiang Zhendong. Mr. Wang came to Mou's home with the idea of independence, democracy and equality, which became a unique landscape. Mou Yankun was framed by several young masters and injured Mr. Wang by mistake. Jiang Zhendong was still worried about the last fight between Yan Kun and Mou Chang, and dared to offend Mr. Mou. In a hurry, he beat Mou Yankun without asking why, but Mou Yankun was not convinced. Mr. Wang enlightened Mou Yankun privately, so that he knew his mother's good intentions towards him, and was informed by Jiang Zhenyu. Jiang Zhenguo was impressed by Mr. Wang's good teaching of his son and went to the private school to thank him in person. Mr. Wang knows how to be polite, but he acts differently from ordinary people. His wife is beautiful, smart and capable, and they appreciate each other and have a long history of affection. Unexpectedly, the scandal between Jiang Zhenduo and Mr. Wang spread all over the manor. The first wife warned her daughter-in-law from the personal experience of a n experienced person that the only way out for her is to cut off her love affair and keep her family business. Jiang Zhenduo tearfully promised to give up and make Yan Kun the head of the Mou family. The first wife smiled with relief and quietly leaned on Jiang Zhendong's shoulder to return to her hometown.

With the death of the first wife, Jiang Zhenduo, a young widow who was the head of Mou's manor, was isolated. In grandpa four's view, it is an excellent opportunity for him to completely eradicate Jiang Zhendong by using his earlier housekeeper Sun and Mr. Wang. Grandpa four failed to make a plan and gave birth to another plan. Fourth master lied to second master that the eldest wife had left a last word to get rid of Mr. Wang.

As a matron, Jiang Zhenduo chose the latter in the face of love and family interests. I just accepted Mr. Mou's ideas, but I kept my love in my heart. Later, when Mr. Wang left the manor to study abroad, and returned to the manor to visit Jiang Zhenduo eight years later, he brought the new concept of emerging industrial development to the wealthy family, brought new revolutionary ideas to the grown-up young ladies, and laid the ideological foundation for the children to leave the manor in the future and resist Japan and save the country.

The second master Mou Zongsheng and the fourth master Mou Zonghao tried their best to make things difficult for Jiang Zhenduo, the head of the company, and made moves again and again, which was solved by the wealthy family again and again. Their heavy punches were like hitting cotton. On the contrary, when the second master Mou Zongsheng was kidnapped by bandits, the fourth master Mou Zonghao was detained by the government fraudulently, and the fifth master Mou Zongteng was accused by the troupe to the government, the wealthy family still stood up, took on the responsibilities and obligations of being a family member for several masters, and tried to reconcile the contradictions within the family as much as possible, and finally let her uncles accept her as the head of the family.

For the farmers of the Mou family, Jiang Zhendong adopted the management method of combining rigidity with softness, which not only gave them the basic conditions for survival, but also made profits as much as possible. In order to get more grain, Jiang Zhendong introduced high-quality varieties, improved agricultural production tools, built dams and stored water, which made the family prosperous in a certain period of time. When Yan Kun, his son, died, Jiang Zhenyu began to consider adopting Mou Yansheng, the son of Luan Yan, to train the next generation of heads of the Mou family. She taught Yan Sheng the history of ancestral training, the methods of land management and the secrets of managing the family, hoping that he could inherit his ancestral business and grow stronger one day. Five years later, Yansheng had a deep understanding of land management and family management. At the ceremony of officially handing over the head, Su Xiaohong brought the news of an all-round outbreak in War of Resistance against Japanese Aggression. Every man is responsible for the rise and fall of the country. Yan Sheng gave up the position of the head of the Mou family at the critical moment of the Chinese nation's life and death, and went to Yan 'an with Su Xiaohong, joined the Eighth Route Army and went to the battlefield of resisting Japan and saving the nation.

In that stormy era, the Mu family declined day by day. The oppression of the government and warlords, the looting of bandits and thieves, and the forced occupation by Japanese devils made Jiang Zhenyu exhausted. Witnessing the fading flowers and the fading family, the young housewife, who was unwilling but unable to return to heaven, was persuaded by Mr. Wang, who had been with her for decades, to leave the manor. Mr. Wang carried Jiang Zhenduo, who was old and frail, into the carriage. Jiang Zhenduo took the silver hairpin given to her by Mou Jin when she just married to Mou Jia, hugged the relic of her son Yan Kun, and stood beside her with the umbrella given by Guqin and Mr. Wang. They left the manor in the sunset and twilight, and gradually drifted away.
