To encourage parents to buy school uniforms, we need to actively communicate with them first. Explain to parents the importance of class uniforms and their role in student unity, identity and campus culture. Class uniforms can enhance the unity and cohesion among students. They can make students feel that they belong to a team and pursue common goals. Class uniforms can be used as a symbol of students' identity, making them easier to identify and identify on campus. This helps to establish order and security in schools. Parents' opinions and suggestions can be considered when choosing class clothes. Provide different styles, colors and sizes to meet the needs of different families and students.
