Gov 3.0 will be holding a public exhibition called Citizens’ Experiential Ground (정부3.0 국민체험마당) at the COEX Convention & Exhibition Centre in Gangnam-gu, Seoul this June, and Ji Chang Wook is scheduled to make a surprise appearance.
Going with the slogan “The Government at your fingertips”, the exhibition will feature numerous interactive activities and IT exhibits for citizens to get to know more about Gov 3.0’s services. Among the activities planned is a “guerilla event” with Ji Chang Wook, meaning that he will make a surprise visit sometime during the event’s run.
In addition, Ji Chang Wook will be holding a fan sign during the exhibition. The fan sign will take place on 20 June from 12pm to 1pm.
