NAHF conducted teacher training for 34 elementary and junior high school teachers selected from 17 provincial and provincial offices of education from October 23 to October 26. The collective training was replaced by online education, and the Dokdo tour was conducted while thorough prevention and countermeasures against infectious diseases were prepared. As a result of the survey conducted on 29 people, they showed high satisfaction in strengthening their competence such as cultivating knowledge about Dokdo, improving professionalism, and changing awareness level. In addition, there were many opinions that the training would continue every year so that teachers could actively utilize the contents of the training in Dokdo-related classes.
