When General Secretary Kim Jong Il visited the factory in April Juche 90 (2001) they were honored to meet him. They were working as machine operators at the shop.

Kim Jong Il put forward the couple as innovators. He said they did not leave the machines during the Arduous March and the forced march, finding the family's happiness in devoting themselves to the prosperity of the country. His deep trust and loving care encouraged them to great merits.

To carry out the tasks set forth by Kim Jong Il during his on-the-spot guidance, the couple contrived and introduced dozens of technological innovation proposals and greatly contributed to enhancing the efficiency of the generating equipment and ensuring the stability of the electric power system to the maximum.

Kim Sung Gi is making redoubled efforts to repay with greater innovations the loving care and trust reposed by Kim Jong Il in the workers.
