An Argentinean family that has been traveling around the world for the last ten years has arrived in Busan.

Herman Zapp, his wife and four children arrived Sunday in the South Korean port city, which is the first stop of their two-year trek across Asia.

The couple, former salaried workers, set out on a world tour ten years ago.

Each of their four children was born in a different country during the couple’s journey. The children have been educated while on the road through both home and cyber schooling.
