From 1998 to 2015, China's forestry industry has undergone tremendous changes in the past 20 years. During this period, Gu Changshan (played by Guo Tao) adopted Xingjie (played by Zhang Wanyi), the son of his partner who died in the line of duty. After hesitation, the Gu family finally decided to support Xingjie to continue his studies outside. The layoff crisis also ended with some young people leaving first. Those who stayed, led by Gu Changshan, started a "family ecological forest" to temporarily solve the livelihood crisis. In 2007, the transformation reached a new node. In order to protect the ecology and improve people's livelihood, the remote forest area immigration project began, and the 923 team once again faced the proposition of going out. Xingjie was also pulled back to the mountains. After resolving the crisis of his family, Xingjie took on the task of mobilizing immigrants and found his own value in it. He was determined to stay and shoulder the mission of forestry reform. Later, under the background of comprehensive logging restrictions in 2014 and 2015, Xingjie actively responded to the call of "Green waters and green mountains are worse than mountains of gold and silver", and led his family and more people in the forest area to a better new life.
