Editor's note: From Sept 11 to Sept 20, four China Daily reporters went to the Sino-Russian border and Sino-DPRK border in three provinces in Northeast China. They traveled more than 4,300 kilometers along the border area to cover the life and work of soldiers stationed there. This is part of a series of reports from the front line.
For the young soldiers stationed on top of Changbai Mountain in Jilin province, Zou Aimin is a comrade who stands shoulder to shoulder with them.
The 30-year-old graduated with a PhD from Jilin University in 2011 with a major in telecommunications. He applied to come to the outpost last year and is one of the few border defense soldiers in the province who has achieved such a high level of education.
"The toughest environment provides the best opportunity to mature," he said.
The Changbai Mountain outpost is the highest in Jilin and stands at 2,622 meters above sea level.
Heavenly Lake, known as Tianchi Lake in Chinese, is at the top of the mountain, and its breath-taking scenery attracts many tourists. The lake lies in the crater of a volcanic cone on the summit of the main peak of the mountain, and it presents a unique photo opportunity to tourists, especially in the summer.
