Ko Yong Suk, the first hero in the textile industry, has completed the daily plan at over 500% everyday even under difficult conditions of wartime and received the Title of Labor Hero in February, 1953.

During the period of the fulfillment of the three-year plan for the postwar rehabilitation and development of the national economy, weavers and spinners like Kim Pong Rye of the then Pyongyang Textile Mill and Sin Pok Sun of Kusong Textile Mill carried out the multi-spindle and multi-machine tending campaigns and ranked themselves among labor heroes.

During the 1960s, many labor innovators including Pyongyang Textile Mill weavers Ri Hwa Sun, Sung Chang Suk, Pak Kum Ok, weaver Ko Kum Sun of Kusong Textile Mill and spinner Yun Kyong Hwi of Sinuiju Textile Mill won the Title of Labor Hero by over-fulfilling the three-year plan, five-year plan and successively the first seven-year plan ahead of schedule.

In the 1970s, dozens of winners of the Title of Labor Hero were produced, including 8 winners each from Pyongyang Textile Mill and Sinuiju Textile Mill.

Weaver Mun Kang Sun of the Pyongyang Kim Jong Suk Textile Mill was the first winner of the Title of Labor Hero in the new century.

For over 10 years, she has over-fulfilled the yearly plan every year.

Just like the Labor Hero weavers of the previous generation who actively carried out the multi-spindle and multi-machine tending campaigns, hundreds of women weavers are bringing about innovation at their workplaces and have fulfilled the yearly plan for this year as of July 28.
