I found that via "‘Frost Boy’ in China Warms Up the Internet, and Stirs Poverty Debate" (NYT).

The boy Wang Fuman is 8 years old. The distance he walks to school is 2.8 miles ("through mountains and streams"), and the temperature cited in the film clip -9° centigrade is 16° Fahrenheit. Chilblains are a skin inflammation that clear up when the weather gets warmer.
