The linked notice is titled 关于政协十三届全国委员会第三次会议第4404号(教育类410号)提案答复的函 教师提案〔2020〕475号 http://www.moe.gov.cn/jyb_xxgk/xxgk_jyta/jyta_jiaoshisi/2021...
About the Political Consultative Conference's 13th National Committee's third session, answer to the 4404th proposal (410th on education). Teaching proposal no. 475 (2020)
Yes, no doubts about its ultimate goal indeed.
The answer begins:
您提出的《关于防止男性青少年女性化的提案》收悉,现将涉及教育部业务部分答复如下:
Having received and read your "Proposal on the prevention of the feminization of male youth", the answers to the parts concerning the Ministry of Education are as follows:
(Then there's a bunch of blabla about improving school sports and whatnot, without any references to gender.)
So someone (who?) was concerned about feminization and asked the Ministry of Education to do something about that and they responded.
The BBC seems to have mistaken the title mentioned in the response for a statement of the Ministry of Education's official policy.
Maybe I should submit a "Proposal to replace Google Translate by fluent Chinese speakers" to the BBC so they can publish a headline "BBC to improve its reporting on China" but I'm not holding my breath.
