Saying goodbye to the birds and the bees

Despite criticism that a sex education textbook is too graphic, parents and professionals have united in its defense. Yang Wanli reports.

"Every time I express my belief that sex education should begin at primary school level, many of my friends are stunned, almost open mouthed. They say 'Oh, my goodness! How can we allow these innocent kids to learn about sex?'" said Li Ming, a sex education teacher at Xingzhi Primary School in the Beijing's Daxing district.

Recently, the school has been targeted as a result of its use of a sex education textbook, even though it was published 10 years ago.
