They had a meeting to take pledge at the plaza before President Kim Il Sung's statue of the Samjiyon Grand Monument on Saturday.

A letter to Supreme Leader Kim Jong Un was read out at the meeting.

The letter said that the period of the study tour of the revolutionary battle sites in the area of Mt Paektu was the unforgettable days when the participants in the tour thoroughly prepared themselves to be reliable and able political activists like the peerlessly great men and keenly grasped the revolutionary spirit and indomitable will of the anti-Japanese forerunners and historic importance of education in the revolutionary traditions.

The letter noted that the participants solemnly vowed to fulfill their mission and duty as party information workers struggling in the great era of Kim Jong Un, true to the pledge they took during their march to tour the revolutionary battle in the area of Mt Paektu.

The letter was adopted.
