This setting is helpful to establish a complete education system and provide a smooth educational path from primary school to secondary school and then to university. Usually, affiliated primary schools are connected with universities or middle schools in terms of teaching resources, teachers and teaching concepts, providing students with better education quality and development opportunities. Affiliated primary schools can enjoy some educational resources of universities or middle schools, such as teacher training and the enjoyment of teaching equipment. At the same time, this connection also provides more opportunities for primary school students to visit universities and communicate with university teachers and students, which is helpful to stimulate students' interest in learning and further career planning.
