When respected Supreme Leader Kim Jong Un together with Ri Sol Ju arrived at the school, its students and teachers who were planting trees broke into cheers of "hurrah!"

He met students and kindly asked about their ages, grades and study and organizational life with fatherly love, patting their cheeks.

Saying that today is the significant Tree-planting Day when President Kim Il Sung took the lead in the tree-planting campaign, he added that students of Mangyongdae Revolutionary School came into his mind when he was thinking of where he would plant trees on the significant day and he visited them.

He noted that the students of the school who are growing to be successors and backbone elements of the revolution should duly take the lead in planting trees, too.

He said that the teachers should lead the students to devote their sincerity and enthusiasm to the tree-planting with extraordinary awareness that they should display their clean conscience and ardent patriotism before planting trees and with will to take good care of woodland even if their bodies may serve as roots and base manure.

He noted that only when one has warm love for the country from one's childhood, can one become a true patriot and a genuine official desired by the Party who does any work oneself for the prosperity of the country at any post assigned to one by the Party in the future.

He taught the students in a way easy to understand, saying it is possible to ensure the rate of rooting when trees are planted in line with the scientific and technical requirements and what is important in tree planting is not how many trees are planted but how many trees are rooted.

Then he personally planted trees for a long while, digging a hole, watering and tamping.

The students, encouraged by his guidance, hastened their work.

Looking with attention at the planted trees one by one, he praised all of the students for doing good work. He said they would recollect today, seeing the trees that grew tall when they visit this place as adults.

Enjoying a bird's-eye view of the school clad in thick verdure, he said that the school has a thick woodland and now there may be no space for planting trees.

He told officials to let the students visit the places associated with the immortal leadership exploits of President Kim Il Sung and leader Kim Jong Il including the Kumsusan Palace of the Sun and plant trees there, and tour modern Tree Nursery 122 of the Korean People's Army so that they may learn the scientific way of planting trees.

He urged the students who are growing, drinking water and breathing air in Mangyongdae to set an example in the forest restoration campaign.

He set forth tasks which would serve as guidelines for the school's upbringing and education and management and operation.

He had a photo session with the students of the school.

Accompanying him were Hwang Pyong So and Kim Yong Su.
