O-genki desu-ka? (Are you fine?)

ya surely "O-genki desu-ka?" means "how r u" in japanese. but in daily life, japanese never say so cause its too literaly like "how do u do" in English. so we dont have good way to say "how r u" in practically. i suggest u to say "ohayou(gozaimasu) / konnichiwa / konbanwa/" = "good mornin / hello / good evenin" these r easy and acceptable^^
