Hopae

Certain military officials were required to wear hopae in 1391 (imitating a similar practice by the Yuan dynasty) and its further implementation was continually raised by the Joseon government from 1398. One game played with dominoes in modern Korea takes its name from the hopae. People of different social classes wore different coloured tags. The yangban class wore yellow, high-ranking yangban officials wore ivory while the lower-ranks wore ones of deer horn. Commoners wore small wooden tags while slaves carried large wooden ones. == References ==
