One day in October 2014, the respected Comrade Kim Jong Un looked round a junior middle school in the newly-built Wisong Scientists Residential District.

Kim Jong Un dropped in at a classroom on the first floor to learn about its construction and school fixtures. Unexpectedly he told an official accompanying him to put a ball-pen on a desk.

When he lifted the top panel of the desk, the ball-pen rolled down the floor of the classroom.

He said that if students lifted the top panels of their desks to take out books and school things from their drawers, books and school things on the top panels would fall down. He told the officials that it is necessary to make a raised part or groove on the upper part of the top surface, otherwise, pencils or ball-pens on the desks could roll down the floor even if they were touched a little.

Looking up to him, the officials keenly realized that the work for the rising generation should not be overlooked even in the minutiae. -0-
