According to the nine-year compulsory education policy implemented by the state, students should not pay tuition and books in primary school. The policy aims to ensure that every child has the opportunity to receive basic education, reduce the financial burden on families and promote educational equity. Government grants and subsidies provide free textbooks and learning materials to schools to ensure that students get the necessary learning resources. This arrangement is conducive to improving the level of universal education and promoting the development and growth of all students.
