Hong Myung-Bo secured his first win as South Korea boss with a 4-1 victory over 10-man Haiti in Incheon on Friday.
The South Koreans were unsuccessful at the East Asian Cup in July, scoring just one goal in their three games, and also slumped to a 0-0 draw at home to Peru last month.
However, they finally found their goalscoring touch at Sungui Arena Park, as Bayer Leverkusen forward Son Heung-Min struck twice, with Koo Ja-Cheol and Lee Keun-Ho each finding the net from the penalty spot.
It was not all plain sailing, however, with Kervens Belfort striking late in the first half to send the teams in level at the break.
Hong chose a relatively inexperienced starting XI, with the experienced trio of Lee Chung-Yong, Kwak Tae-Hwi and Koo left on the bench, while goalkeeper Kim Seung-Gyu was handed just his second international cap.
Son got his side off to a good start as he found the net with a superb effort from outside the area after 21 minutes, but the jitters set in as a defensive lapse left Belfort free in the area to slot home an equaliser.
Koo put the hosts back ahead from 12 yards after Lee Chung-Yong was fouled in the area just five minutes into the second half.
Things got worse for the visitors five minutes later as Yves Desmartes was dismissed for his second booking, before Bolton winger Lee Chung-Yong was again felled in the box and Lee Keun-Ho converted from the spot.
Son had the final say 17 minutes from time to lift some of the pressure off Hong ahead of their friendly clash with European side Croatia on Tuesday.
