Online courses increasing in popularity

When Zhang Yang went on maternity leave last April, she also signed up for an online learning course.

While looking after her 1-year-old takes up most of her time now, Zhang is happy to continue her online classes in art history with Peking University.

"I've found the course quite fascinating as I also took the subject in college," she said. "Plus, class discussions can be quite interesting because sometimes you discuss the topics with people from different parts of the world."
