One day in November 2016, the respected General Secretary Kim Jong Un visited the Samjiyon Schoolchildren's Palace.

In a hobby group room of the palace, the General Secretary asked if the room had no thermostat, pointing out that its temperature was too high.

The officials could find no word to reply since children, teachers and parents there all thought that hot temperature is all right under the winter condition.

But, Kim Jong Un was concerned to provide the schoolchildren with a more suitable indoor temperature.

Looking at the officials with kindness, he earnestly called for establishing an integrated control system so that the temperature of hobby group rooms could be automatically adjusted.

In the fine art group room, he said that a combined control room should be set up at the palace and a temperature sensor installed in every hobby group room to monitor the room temperature in real time and automatically control it so that the temperature of rooms can be always kept at 21-22 degrees C even in winter.

Looking up to the General Secretary who takes such warm care of the children, the officials could hardly repress their surging emotion. -0-
