Enhe Hada Border Police Station, called "China's northernmost station," sits in the uninhabited, freezing Greater Hinggan Mountains along the China-Russia border. Winter temperatures can fall to –58 degrees Celsius, with only 81 frost-free days each year. 

Generations of officers have faithfully guarded this frontier, becoming an enduring part of its history. While families across the country reunite for the Spring Festival, these forest guardians remain on duty, quietly safeguarding the border.
