Local industrial factories have been placed on a modern and scientific basis to lay a firm foundation for reenergizing production and improving the standard of people's living. The county seat has taken on a new appearance to suit the specific features of a county.

President Kim Il Sung provided field guidance of devotion to the county, once known as remote mountainous county, more than a hundred times in his lifetime with a noble intention to turn it into a model to be followed by all other counties.

There began a new history of mountains of treasures in the county under his care. As a result, the Changsong joint meeting of local party and economic officials was held in the county in August 1962.

Leader Kim Jong Il made sure that the spirit of the joint meeting was fully displayed generation after generation. He gave an instruction to the county to raise a new torch for effecting a dramatic turn in the local industry in November 2010.

The dear respected Marshal Kim Jong Un has led a drive to face-lift the county as required by the building of a thriving nation so that the year 2012, the 50th anniversary of the joint meeting, may shine as a proud year and a year of new changes in the development of local industry.

All local industrial establishments in the county have undergone dramatic changes as required by the new century in a matter of little over one year.

All production processes at the foodstuff factory ranging from feeding of raw materials to packing and forwarding have been automated and its overall processes sterilized to ensure high quality and hygienic safety of products.

Its textile mill has installed new type machines. Technological updating has made brisk headway at all industrial establishments in the county including paper, furniture and chemical and daily necessities factories.

There has sprung up a new food processing factory. All its processes computerized, the factory mass-produces processed meat and vegetables, varieties of soft drink, and confectionary.

A garment factory with big capacity has been built to meet the county's need for school uniforms and solve the issue of clothing by itself.

The appearance of the county has changed beyond recognition.

The county erected a mosaic depicting the portraits of the smiling peerlessly great persons. The Changsong revolutionary museum and the county hall of culture have been successfully renovated as centers for the education in the revolutionary history and people's cultural and emotional life.

The Changsong Restaurant and a noodle restaurant built with Korean style roofs in the center of the county seat add to the beautiful landscape of the township.

There sprang up the Undok Health Complex with all welfare and service facilities, a children's hall, kindergarten and nursery.

The library, county people's hospital, sanatorium, commercial and catering network, public buildings and dwelling houses have also been renovated as required by the new century.

A great success has been made in the land management.

The eye-opening changes in the county promise a socialist land of bliss where all varieties of consumer goods are mass-produced at the local industrial factories and the people enjoy happiness in their modern houses.
