It happened on one day in May 2009 when Chairman Kim Jong Il visited the Komdok Mining Complex.

That day he was much pleased to see the room dedicated for the miners of the Kumgol Mine.

He made rounds of the bathroom and sauna. At the dining hall for the innovators he smiled, seeing all sorts of foods on the dining table. When official informed him of the successes gained in the welfare supply service, he said that they have done very good and the miners would be delighted with it and the health of the workers, precious treasures of the Party and revolution, was all in all to us although the buried treasure was valuable.
