At the end of the year, she participated in a dance number (with five other first time winners) at the annual KLPGA Awards show.

Jung had a solid 2012 campaign. She played at the US Women's Open and earned a respectable 21st place finish in what was probably her first Major. On the KLPGA, she finished 18th on the money list, earning about 175 million won. She did not win, but had six top tens, including a second place at the Doosan Match Play (losing to Char Young Kim in the final). She only missed one cut as well.

Jung finished 35th on the 2013 money list, carding three top tens. Her best finish was a 4th at the KDB Daewoo Financial Classic. In the Fall, she successfully made it through JLPGA Q-School and played on the Japanese tour in 2014.

Jung had an solid rookie season in 2014, finishing 26th on the money list with 37 million yen earned. She had only three top tens (best finish: tie for third), but produced a whole bunch of top 20s. She also played the LPGA's Mizuno Classic, finishing 43rd.

It looks as though Jung finished 71st on the JLPGA money list in 2015, but the information on the JLPGA website is incomplete for her. She did not play in Korea in 2015.

Jung returned to the KLPGA full time in 2016, and had a decent season. She finished 34th on the money list with around 183 million won earned. She had four top tens, her best finish a second place at the Mun Young Queen's Park Championship. She also finished 4th at the big money BMW Ladies Championship.

Jung had another decent season on the KLPGA in 2017. She earned slightly more than she did in 2016, 189 million won. She had four top tens, but by far her best finish came at the Korea Women's Open, the year's first Major. She finished 2nd there. She also notched a tie for 9th at the LET/KLPGA joint tournament in China, the World Ladies Championship.

Jung had an average season in 2018. She finished 44th on the money list with about 162 million won earned. She had two top fives during the year. Jung's 2019 season was much the same. She again finished 44th on the money list, this time earning 140 million won. She had three top tens, her best being a 4th place.

In 2020, the world was hit with the Covid19 pandemic. All sports leagues, including the LPGA and KLPGA, were massively affected by it; many events were canceled or shifted around the schedule, and fans were forbidden from attending. Jung played as many events as she could in Korea. By far her best finish was a 2nd place at the S-OIL, but that didn't count as official because it was rain-shortened to just 18 holes. She had one other top ten. She earned 87 million won, good for 58th place on the money list. She maintained her tour status for 2021.

Jung's 2021 season was more of the same. She finished 57th on the money list, earning a little more than 133 million won. Her best finish was making the final four at the Doosan Match Play, where she finished 4th.

Yeon Ju had a slightly better 2022 season. She finished 51st on the money list, earning nearly 170 million won. She had one top ten, a 6th at the Pak Se Ri Invitational. In 2023, she made a shade under 80 million won for the year, 92nd on the money list. Her best finish was a tie for 14th.
