A school in Nanjing plans to order Korean-style school uniforms for students, but parents were against the move, believing that the new uniforms looked too good and would encourage early romances among the students.

Parents: “My daughter was so excited about the Korean-style uniform, saying it’s her dream to wear a miniskirt to school every day,” a mom said. “My daughter also called her classmates to talk about how handsome the boys looked in the uniforms! If the students wear such beautiful uniforms, how can they concentrate on their studies?”

School: we had to stop the plan because many parents were strongly against it. Some parents thought it was just a way for the school to make money, and others thought the new uniforms would take students attention away from their studies.

Students: the students were very disappointed about the school’s final decision. They thought the sportswear uniforms made them look androgynous( 兼具两性的). They said the Korean uniforms had many advantages such as raising interest in class and lifting confidence.

As for concerns about romance, the students believe that love is love and has no relationship to the uniforms.

The Department of Education: We don’t have a unified standard for school uniforms. The schools can choose their own styles. Either sportswear or other uniforms are OK. Currently, most middle and elementary schools in Nanjing have sportswear uniforms.

Expert: Fashionable school uniforms can increase students’ interest in learning. Parents don’t need to worry too much about early romances. Today’s primary and middle school students have strong personalities and their appreciation of beauty is rapidly forming. A fashionable uniform can foster(培养) their sense of belonging to the school and reduce their resistance to the school’s management.

But we don’t have to follow Korean or Japanese styles. We should design our own Chinese style uniforms.
