As concern mounts over a crisis of confidence among male pupils, one kindergarten is working to help them discover their masculine side. Wu Ni in Shanghai reports.

Ni Jieji, a 23-year-old kindergarten teacher, has seen many children screaming and wailing when they first enter school, but the unusual timidity of Xiaolei still surprised him. Ni found the 5-year-old boy seldom talked with his classmates. In class, he seemed afraid to speak. "He didn't even dare to ask to leave when he wanted to go to the toilet," Ni recalls.

Xiaolei might be an extreme case. However, Xu Hui, the principal of Haoertong Kindergarten in Shanghai's Pudong New Area, noticed that on the first day of a new school year most of the children crying are boys. Moreover, boys are slower to get integrated into the "small society" of kindergarten than girls.
