A wife in part time job said that her student number was large because numbering in male was followed by numbering in female, when she was an elementary student.
She added that I don't agree with numbering by mixed gender. Male should lead the society, which is contrary to the opinion of Yoko Tajima
※Yoko Tajima is a famous feminist in Japan.
When I was in elementary school, I was assigned to the student number arranged by both sex and mixed gender.
Her claim is that student number assigned by sex seems to be clearer than that done by mixed gender.
