Shanghai's all-boys classes to double enrollment(2)

"Boys told me they have more channels to communicate with girls than I thought," Lu said. "One boy goes to next-door classes to tell girls stories, while another is keen to show girls how to dance."

Boys also made progress in their academic performances. Lu said that among the top 20 students in the grade with best academic performances, eight were from all-boys classes at the beginning of last semester, and that number grew to 14 by the end of the semester.

All of these will help with the school's enrollment, which will start on Saturday, he added.
