Border police officers put their knowledge to work

The Beiji border police station in Heilongjiang province - China's northernmost police station - was honored as a model unit by the State Council and the Central Military Commission in May.

Fourteen border officers patrol the area, helping residents and a growing number of tourists who visit its scenic attractions.

Zhang Chunmao, a 26-year-old border officer, has been at the Beiji police station for two and a half years.
