One day in June 2017, the respected Comrade Kim Jong Un visited the Kangso Mineral Water Factory and saw the newly-built process of producing plastic-boxed mineral water.

After watching a worker cover vinyl for sealing up mineral water boxes, Kim Jong Un went up to the worker.

Then he looked at the worker's dress for a while, touched the deep blue smock, and said that it was too dark.

The employees and officials of the factory were indifferent to the smock.

Kim Jong Un said that the workers' smocks of the Kangso Mineral Water Factory should be made neat and tidy in conformity with the characteristics of the drinking factory and instructed an official concerned to make the designs of smocks and present them to him.

Later, he personally examined the designs of smocks of its employees and made sure that they wear white upper clothes and light blue trousers.

The designs are associated with the warm affection of Kim Jong Un who is working heart and soul to provide the working people with the most cultured and civilized environment for production and life. -0-
