While giving on the spot guidance to the construction of the Grand People’s Study House in the finishing stage on September 26, Juche70(1981), President Kim Il Sung said that the luminous intensity of the reading rooms was low and taught the officials to increase the luminous intensity or install a reading lamp on the table.

He said that it was very important to increase the luminous intensity of the reading rooms in order to protect the readers’ eyes and not to cause their eye strain.
