Wherever you watch the South Korea versus Spain World Cup quarter-final today, don't forget these words: Dae Han Min Guk.
The words mean 'South Korea' and if you want to get behind the remaining Asian team in the tournament, be like the Red Devils' fans and sing it loud and proud.
The popularity of the Red Devils is soaring - even Hong Kong has a cluster of followers who will be screaming support for their team today.
Grade 11 students at the Korean International School in Sai Wan Ho are utterly mesmerised by their heroes - as you would expect.
The 16- and 17-year-olds have geared up for the biggest match in their home nation's history by designing posters that declare their pride.
'Go to Yokohama!' blares a poster in reference to the final scheduled for June 30 in the Japanese city.
