During the frigid winter in the Greater Hinggan Mountains, located in Heilongjiang province, many forestry workers stick to their posts in forest management and production. They remove diseased and rotten wood while cultivating the forest. Eleven forest workers from the Daxigou conservation area under the forestry bureau of Huzhong district entered the operation site on January 2 to carry out forest cleaning work. They live in temporary tents for nearly 20 days without phone coverage or digital connection to the outside world.
