The field command officials gave shape to their assignment for supplying the aggregate in time, and have set practical examples to arouse the working masses to the construction progressing at a high speed.

The aggregate production brigade launched a brisk socialist emulation among battalions and working groups and carried out the self-checking and self-repairing tenaciously to increase the operation rate of shovellers and excavators 1.2 times than before. As a result they are securing a large amount of gravel every day.

The workers of the provincial construction mechanized brigade, too, are extracting thousands of cubic meters of aggregate every day.

And many people in Hamhung City have turned out in the greenhouse farm construction.
