Everywhere in the DPRK can be seen working people who devote their all to the country, without expecting praise or reward, including farmers who produce high crop yields by cultivating land all their lives, forest rangers who plant green forests in the deep mountains, coal miners cutting coal in deep pits, builders at construction sites of major projects and watchmen who ensure the safety of railways in remote mountain railway stations throughout their lives.

Among them is Kim Jong Nam, head of the Jicho meteorological observation station of the South Hamgyong provincial hydro-meteorological branch.

He works on a plateau well over a thousand metres above sea level and scores of kilometres from the town. Kim and his family stand guard over the post in this out-of-the-way place with changeable weather. Since he decided to follow in his father’s footsteps and volunteered to work here, he has devoted himself to meteorological observation. And now his eldest and second sons are taking over the job after their demob, following in their father’s footsteps.

The family of Kang Yong Su, a forest ranger of the Unsan County Forestry Management Station, has planted green forests for three generations. His father is known to the whole country as a prototype of the Korean feature film "Forest Is Swaying". During the Fatherland Liberation War, he could not leave the bald mountain whose forests were burned by the bombing of the US imperialists. So he decided to stay in a remote mountain village, though it was not his native place, and planted forests all his life. Following in his father’s footsteps, Kang became a forest ranger. He could have selected a better job as he was a demobbed officer. But the forests associated with his father’s painstaking efforts and patriotic soul were more precious and he chose the job and worked hard to lead a worthwhile life like his father.

Honoured with the titles of Merited Forest Ranger and meritorious person of socialist patriotism, he still works to cultivate the forests at the age of over 60 in order to return the favour shown by the country.

Like his grandfather and father, his son also began to work as a forest ranger.

The family of Yu Yong Chol and his four brothers, coal miners at the coal mine for supplying coal to Jagang Province under the Kaechon Area Coal-mining Complex, has been working in deep pits for three generations. Today their names are known to the whole country along with the patriotic movement for increasing coal production. True to his father's request to become the eldest son of the country before that of a family, Yu Yong Chol and his brothers all became coal miners and took the lead in the movement.

There are many other families who have followed the road of devotion for the prosperity and development of the country, such as teachers' family, road keepers’ family and smelters' family.

And it has become the unanimous desire of the Korean youth and the trend of the times to volunteer to work in the difficult and labour-consuming sectors at the call of the country by inheriting the patriotic tradition of the preceding generations.

As there are many such patriots and the spirit of patriotism is carried on generation after generation, the DPRK dynamically pushes ahead with the building of a powerful socialist country, overcoming all difficulties.
