Two number systems, one brain

Native for hours and age, Sino for money and minutes. The counter field guide closes the gap.

Korea runs on TWO number systems — native (하나 둘 셋) for hours, age, and counting; Sino-Korean (일 이 삼) for money, minutes, and floors. The counter you pick changes everything.
