In 2008, the eleven-year old Chung saw with the Australian Open victory of Novak Djokovic his first tennis match on television. He then began to get enthusiastic about tennis and the Serbian player who is still his role model today. Chung began to compete in tennis with his older brother. He was also advised to practice the sport by his doctor because Chung had had a weak eye since childhood. The green planks around the tennis courts should soothe his irritated optic nerve. Chung's white sports glasses, which he regularly wears to his competitions, later became his trademark.
In his junior years, Chung Hyeon reached the final of the individual competition of Wimbledon 2013 , which he lost to Gianluigi Quinzi .
His final breakthrough as a professional tennis player came in 2015. He won four tournaments on the ATP Challenger Tour and ended the year in 51st place in the world rankings. In 2016, he was thrown back from an ankle injury and dropped out of the top 100 in the world rankings. The year 2017 was again much more successful. He finished the year in 54th place in the world rankings and achieved the greatest success of his career to date by winning the first edition of the Next Generation ATP Finals .
