One day in late September, at the "Children's Home" in Linbing Zu Village, Dongshan Town, Qilin District, Qujing City, Yunnan Province, more than 10 children were happily "competing" against a square paper with 25 numbers written in disordered order. Whoever can quickly point out 1 to 25 in order will win. This is one of the activities of the "Children's Home" focus improvement group, the Schulte training method. This summer, the "Children's Home" in Lin Bing Zu Village organized the "Spring Mud Plan" summer camp. In the morning, I tutor children with homework, and in the afternoon, I organize them to draw, play with colored clay, conduct scientific experiments, and sometimes take them out to collect fungi and make specimens. The "Children's Home" is operated by the Qilin District Chuxin Social Work Service Center. Founder Zheng Hongqin introduced that social workers pay attention to cultivating children's expression, organization, and coordination abilities when planning activities, and let them experience the joy of creating value. At the same time, the social workers at the service center observed and summarized the problems of children's lack of focus and self-confidence, and carried out a series of targeted activities after the start of school. Since its establishment in 2017, the "Children's Home" in Lin Bing Zu Village has continuously served 300 left behind children in the village, and the richness and scientificity of its organizational activities have been continuously enhanced. The story of Lin Bing's village is a small segment of the protection of minors in China. Since the 18th National Congress of the Communist Party of China, the legal system for the protection of minors has been gradually improved, the work pattern has gradually improved, and social forces have become more abundant. The "six major protections" of family protection, school protection, social protection, network protection, government protection, and judicial protection are integrated and coordinated. The network protecting minors is further weaving and weaving. In 2017, Zheng Hongqin, who had been working in Kunming to assist migrant children, saw a child from his hometown doing homework on the roadside without his parents, and was determined to return to his hometown to serve left behind children. At first, she was alone, with 7 bookshelves, 400 books, and 20 sets of toys donated by caring individuals. Nowadays, the Chuxin Social Work Service Center has 5 social workers, as well as volunteers and interns who regularly participate in activities, and has established "children's homes" in 5 villages in two townships. To address the site issue, the local government and village committee have coordinated to integrate the "Children's Home" with the New Era Civilization Practice Institute (station). There is a spacious venue, tables and chairs suitable for children's height, bookshelves and picture books all over the wall, and children's paintings are posted everywhere, exuding a childlike atmosphere. The children usually stay at school to study and come home on weekends. Therefore, we hold activities on weekends and holidays, and many children are unwilling to leave when they come, "Zheng Hongqin said. At present, Qilin District has established "Children's Homes" in more than 130 village communities, serving more than 2200 left behind children in the entire district, and also has a parent-child reading base. This is true in rural areas, and the same is true in cities. In order to provide suitable conditions, environment, and services for children's growth, the National Development and Reform Commission, in conjunction with 22 departments, issued the "Guiding Opinions on Promoting the Construction of Child Friendly Cities" in 2021, requiring the implementation of 100 pilot projects for the construction of child friendly cities nationwide by 2025. Currently, China
