Hey guys.
Have you heared about battle of Myeong-ryang? General Lee sun shin defeated his enemy with only 12 ships at Uldolmok.
Uldolmok is not a river but a sea. Uldolmok, with narrow and fast currents, had a big impact on Admiral Yi's victory.
Why don't you visit Uldolmok in Jindo, Jeollanam-do, South of Korea?
See the strong currents of the Uldolmok.
