Ko Hyeon Jeong is a South Korean actress. She debuted in the entertainment scene as a Miss Korea runner-up in 1989 and went on to star in Sandglass, one of the highest-rated and critically acclaimed dramas in Korean television history. She retired after marrying chaebol Chung Yong Jin in 1995 and then returned to acting after their divorce in 2003. Go has since regained her top star status in Korea, becoming the highest-paid actress on TV after the success of her series Queen Seondeok and Daemul. Go Hyun Jung graduated from Dongguk University with a degree in Performing Arts. She was a runner-up in the Miss Korea pageant in 1989, which launched her acting career. Her big break came in the 1995 SBS drama Sandglass. The drama dealt with modern Korean history from 1970 to the 1990s and was one of the highest-rated dramas in Korean television history, with average ratings of 50.8% and a peak of 64.5%. People would rush home just to see a new episode, saying, “It’s time to go home”, which meant they had to go home to watch Sandglass. Go returned to television in 2013 with The Queen's Classroom, a remake of the 2005 Japanese drama Jyoou no Kyoushitsu. The story depicts the struggle between a ferocious and ruthless elementary school teacher and her class. In 2014, she began teaching acting at her alma mater, Dongguk University. Back in 2006, she donated a ₩100 million scholarship fund to the school. (Source: Wikipedia) Watch drama online for free.
