Kids camp broadens horizons

7-day program aims to empower the children of sanitation workers

Chang Tianhao recently built a model snow plow - about 10 centimeters high and 26 cm long - for his parents, who are sanitation workers in Beijing.

"I don't like snow, because my mom and dad don't come home on time. With the snow plow, they can finish their work efficiently and get back early to be me," he said.
