Both revolutionary themed, the timelines are close and it shows the time period right before Man of Will so I do recommend watching Nokdu Flower first!
Both are really good Japanese colony Korea area. Hard working solid Korean were being suppressed and harassed by their own Pro Japanese spy. Heartwarming, hard truth stories
Both if this Korean movies has to do with Korean letters. Preserved, teaching, spread the literature to future generation. Both are powerful true story
Both are Korean movies about Korean letter words. So many illiteral plor korean that don’t know how to read or write. Teaching adult to read and write is sweet and powerful.
