In September 2014, Jin became the first amateur to lead a PGA Tour China event. In November 2014, he won the Nine Dragons Open on PGA Tour China, becoming the first amateur to win on that tour. He birdied the 17th hole Sunday at Nine Dragons Golf Club while leader, Brazil's Lucas Lee, made three bogeys over his final three holes.
Jin has also played, and made cuts on, the OneAsia Tour and the Asian Tour. In December 2015, Jin tied for 11th at the Asian Tour's Thailand Golf Championship for his best career finish outside of China.
In his PGA Tour China career, through the 2015 season, Jin has played 18 events, making the cut 13 times and recording six top-10s, including the victory.
Jin won the rain-shortened 2015 Asia-Pacific Amateur Championship at Hong Kong's Clearwater Bay Golf & Country Club to earn entry into the 2016 Masters Tournament. In this tournament, he shot a course record 62 in the first round.
