Jang's fame gained him entry into the royal court at Hanseong (present day Seoul), where selected commoners displayed their talents before the king and his advisers.
Seoul was called Hanseong (漢城) or Hanyang(漢陽) during the Joseon Dynasty, but the city's main railway station opened with the name "Gyeongseong Station" (京城驛) in 1900, which name it retained until 1905.
