One September day in 2013 the respected Comrade Kim Jong Un came to the construction site of dwelling houses for lecturers at Kim Il Sung University.
Looking round in detail every room of a dwelling house, Kim Jong Un stopped at a room for man and wife. Feeling regret at the absence of bed, he asked someone or other why there was no bed in the room.
An official explained that they spared spaces for furnishings of the new comers. Noting that the living rooms should have beds, Kim Jong Un pointed out that there should be 600 beds for the rooms for man and wife and their children as there were 300 households and took necessary measure.
