One family has guarded northern border for generations

In the depths of the Hulunbuir grassland in the Inner Mongolia autonomous region, three generations of a family have guarded a section of border for a century connected by eight boundary monuments -- making an important contribution to the security of China's northern frontier.

Tumen, 55, is currently serving as the third border guard of his family. He said that his family's total patrol mileage had exceeded 100,000 kilometers.
