'Losing weight is really tough'

Wang Yilong, a 17-year-old who has dropped out of college.

I have been at fat camp for 10 days and have lost 5 kilograms so far. I know that's what people would most love to hear when they come to the camp, but I am even happier to find that I now breathe more easily when walking.

I am 1.74m tall and weigh 120kg. When I took the subway, I felt as though the seats were being squashed because of my shape. My friends called me "fatty" and I didn't find it insulting at all.
