Children must learn in advance to avoid being left behind

Mao Liping, 41, is a stay-at-home mother of 6- and 16-year-old sons in Shanghai.

I have learned through bringing up my two sons that children's education has changed quite a lot over the past 10 years.

My 16-year-old boy did not learn any pinyin or math before primary school, but did not fall behind academically. However, if children do not learn in advance today, it will be impossible for them to catch up with the others.
