A primary school in Hangzhou said on Monday it’s pulling a sex education textbook over complaints after gaining recent international attention for both its progressive approach and its graphic content.

Controversy sparked after a mother of a second-grader at the school posted about the textbook on Sina Weibo on February 28, complaining the book contained overly-graphic illustrations of reproductive(生殖的)organs.

The book, published by Beijing Normal University, aims for students aged 6 to13. It had been used in schools for nearly a decade before the recent round of controversy.

In China, sex education often faces resistance, especially from the older generation of parents who used to tell their children that babies were picked up in streets or jumped out from rocks. China’s sex education is considered conservative and schools usually try to avoid the subject, leaving the responsibility to parents or society. Nowadays, the frank description of sexual behavior in a recently-released sex education textbook for primary school students in the city has triggered a wave of parental concern. Is the sex education textbook truly too clearly expressed?

Some people hold that the sex education book should be detailed. Sex education is an important way of teaching children knowing themselves, so we cannot ambiguous words describing the sex. On the other hand, adults see dirty things in the books while students may not. They see things in a different way and we should not judge the books from our perspective. There is no need to avoid sex in education.

Others do not agree. They think it is not wrong to describe sex in direct ways, but the sentences in the book are too rude and are even banned from our website. The wording should be more tender and beautiful in books for children.

As far as I can see, we should be more careful about the sensitive topic, sex education. Different methods should be applied to children of different age groups. We can tell more details about sex to the older children, because they can accept it smoothly, and give more pictures, or tender words to the younger ones.
