The survey by the China National Children's Center and the Social Sciences Academic Press looked at 8,847 school children in seven cities, reported Xinhua.
About 30 percent of primary school students surveyed spend over two hours finishing homework every day, and the proportion is as high as 72.4 percent among high school students.
The survey also found that "study" is the main topic of conversation between parents and children, about 31.5 percent of parents never speak to their children about making friends.
Researchers suggest schools and families should balance students' study and life, encouraging them to participate in sports and entertainment activities.
