• Membership Training (DanYang, Chungcheong-do)

At Aug 19-20, 2024, Members of EmPasLab enjoyed the beautiful scenaries of DanYang, Chungchung-do and delicious food called MaeWunTang (Hot fish soup). We visited Gosu-Cave, one of the big caves in South Korea. At night, we played ping-pong and drink high-ball, whisky, etc... Although weather was very hot, mountains covered with green trees and beautiful NamHan River made us happy. (➡️pictures)
