It was when Chairman Kim Jong Il visited the Ryongsong Machine Complex.

Recalling with deep emotion the glorious development of the complex, Kim Jong Il said that it developed into a leading large-scale machine building base and a “mother factory” thanks to the benevolence of President Kim Il Sung. Listening to the workers who say that they can possibly do everything if they are determined to do it and acquainting himself in detail with a large-sized compressor manufactured by them, Kim Jong Il highly appreciated by saying that they are laudable, capable and competent and the complex can be called the face of industry of the country.
