Sex education textbooks not a matter of jest

"O boy, you are growing taller", a middle-aged woman tells a boy, adding: "Now pull down your pants, and lemme see if your member is growing too?"

This picture with the speech bubbles from a sex education textbook for Grade 2 pupils, was posted by a child's mother on a social media website on Feb 28 to show how "inappropriate" the book was for children. And not surprisingly, it sparked fierce online discussions with many saying the book contains material not suitable for young children.

This prompted the book's editors to post online the full picture from the book which advises children facing such a situation to immediately leave the place, avoid such people in the future and inform their parents of the incident. Still, some micro-bloggers, including Li Tiegen, a commentator, continued their tirade against the book and the boy's school in Hangzhou, East China's Zhejiang province.
