Areas that need improvement
To be sure, there are areas where China can improve. Cultural values tend to keep women from becoming too successful in the workplace.

"But when I go home, I still get asked by my parents and relatives about when I'm going to stop working and find a boy to settle down," she said. "Luckily, they are not my bosses."
