Naju Bong, chairman of the National Missing Persons and Family Finding Association, has returned over 800 missing persons to their families over 35 years. He pointed out the seriousness of the adult missing person problem, which is so difficult that even putting up missing person flyers is challenging, and has actively advocated for related legislation. In 2013, he even conducted a 'self-missing' experiment to raise social awareness about the issue of missing persons. He proposed strengthening the expertise of police dedicated departments and introducing a reward system for long-term missing person cases. Chairman Na emphasized the importance of active public participation in finding missing persons and appealed for help to ensure that loved ones can return home.
