不到黃河心不死(부도황하심불사)

황허에 이르기 전에는 단념하지 않다.
결심을 쉽게 버리지 않다.
목적을 달성하기 전에는 그만두지 않다.
목적을 이룰 때까지 절망하지 않다.
one's resolve will not die until one reaches the Yellow River
not to stop until one reaches the Yellow river
Untill all is over, one’s ambition never dies.
not stop until one reaches one's goal
not to give up hope until one comes to one's tether's end
refuse to give up until all hope is gone
