Sentry post on duty in freezing coldness(2)

At the beginning of 2012, the Hongshanzui sentry post of a frontier defense regiment of the Chinese People's Liberation Army located in the Aletai area in the northwest China's Xinjiang Uyghur Autonomous Region witnessed a 1.2-metre-thick heavy snow. The officers and men of the sentry post brave the freezing temperature of about -30℃ to fulfill their patrolling mission.
