A growing number of young people are becoming overweight or even obese as a result of poor diets and sedentary lifestyles, as Wang Keju reports.

After four months of self-harm, followed by 12 weeks' therapy and almost a year quarreling with her parents, Hong Yuan arrived in Beijing in May.

She had traveled more than 1,760 kilometers from her home in Chengdu, capital of the southwestern province of Sichuan, to attend a boot camp for young people who are overweight.
