Commonly 계십시오 or 가십시요 may follow 안녕히. 안녕히 계십시오: "Goodbye" (when you leave someone at his place) 안녕히 가십시오: "Goodbye" (to someone who is leaving the place of parting) 가십시오 is from 가다 (go) and 계십시오 from 있다 (is, stay) and its honorific 계시다. So you must say 안녕히 계십시오 to someone who is staying at some place for a while. If the other person is going somewhere (home or some other place) you use 안녕히 가십시오, meaning "take care of yourself (on your way)". TV news casters therefore can never say 안녕히 가십시오 since they are addressing people at home (or perhapse office). They must say 안녕히 계십시오 or something else like 내일 다시 뵙겠습니다 (See you tomorrow).

This is Josh and I make mistake error to the post above. sorry, is this form--> 안녕히 가십시요 right?
