The number of innovators is on the steady increase at the light industrial factories in South Hamgyong Province amid a dynamic campaign for increased production to carry out the decisions made at the 8th Party Congress and the administrative policy of the government of the Republic.

Over a hundred workers of the Hamhung Woolen Mill, Hamhung Silk Mill and Hamhung Knitwear Factory finished their national economic plans for two years or yearly plans.

The factories wage a hot emulation, encouraging the introduction and generalization of valuable inventions after setting practical technological innovation goals and giving timely publicity to laudable deeds and innovative successes.
