One day in July 2016, the respected General Secretary Kim Jong Un visited a factory and looked round its combined control room.

Seeing the general interface of the integrated production system on a large display board, he said with pleasure that it is wonderful and that the integrated production system has developed a lot.

An official explained a measuring device to him, saying that all of operators want it to be installed at their machines first.

Listening to the official, the General Secretary expressed his great satisfaction and said it is truly successful modernization when the workers have appreciated after operating equipment.

The official was given a great shock as he had regarded modernization as a technical undertaking for further developing production lines or machinery and equipment, without clear standards.

Looking at the official, the General Secretary stressed that the order of objects to be updated should be set as demanded by the workers.

The official came to realize once again that the people's demands and interests are the absolute standard of all work. -0-
