Zhu Boyong is the chairman of Lisa Clothing Company. For 30 years, he has never abandoned the photos of his sick wife Yang Jing and his mentally retarded child Zhu Bao. Ronghua, a migrant worker, took her mother-in-law and grandmother from the countryside to small towns near the provincial capital to make a living. Zhu Boyong asked Rong Hua to be a nanny. Ronghua's kindness won the favor and dependence of Yang Jing and Zhu Bao. Yin Li, a migrant worker, started as a temporary worker and helped Lisa Enterprise solve many problems. Chen Quan, an unemployed homeless man, was frustrated by the failure of his business. Cheer up with Ronghua's help. He changed his gratitude to Ronghua into love. Rong Hua was deeply confused about marrying her. Yin Li liked Zhu Zhu, the general manager of Lisa, but Zhu Zhu was indifferent. Zhu Boyong used facts to change her erroneous secular notion of despising migrant workers. Zhu Zhu gradually accepted Yin Li. With their joint cooperation, Lisa garment enterprises are becoming more and more prosperous. Rong Hua also took care of Zhu Bao with his ex-husband's mother and grandmother. Small foreign families live in harmony with Zhu Boyong’s family, integrate into big city life, and move towards a harmonious and happy tomorrow together
