Parents express frustration with 'difficult' homework

Some do it on behalf of their children, even though teachers can spot difference

In a small city in China's north-eastern Liaoning province, Xu Tingting has been working on a cross-stitch for days - her daughter's fourth grade homework assignment from her primary school.

Xu said that when it comes to assignments requiring handiwork such as cross-stitch, making waste into useful products, and hand-drawn newspapers, she is usually the one who does it for her daughter.
