[4] They won the bronze medal at the 2015 Rostelecom Cup, qualifying for the Grand Prix Final, which had been expanded as a result of the Paris incident.

Peng/Jin competed in the pairs event in Pyeongchang, finishing seventeenth in the short program and thus missing the free skate by a single ordinal.

With both Sui Wenjing / Han Cong and Yu/Zhang sidelined by injury at the beginning of the season, Peng/Jin were the sole Chinese pair team competing internationally on the senior level.

On the Grand Prix, Peng/Jin began at the 2018 Skate Canada International, where they won the silver medal, finishing ahead of bronze medalists Kirsten Moore-Towers / Michael Marinaro by 0.15 points.

At the 2019 Four Continents Championships in Anaheim, they placed third in the short program behind Moore-Towers/Marinaro and a returning Sui/Han, in consequence of Peng falling on their throw jump.

[10] They also came third in the free skate, making an error on the side-by-side triple Salchow jumps, finishing third overall, their first ISU Championship medal.

[12] They came fifth in the free skate due to Peng underrotating her triple Salchow attempt and finished fourth overall, off the podium, by 1.97 points.

On the Grand Prix series, Peng/Jin first competed at 2019 Skate America, placing first in the short program despite Peng stepping out on and underrotating her side-by-side jump.

[14] They also placed first in the free skate, despite a fall on a throw triple loop, taking their first Grand Prix gold medal together.

[15] At their second event, the 2019 Cup of China, Peng/Jin placed narrowly third in the short program after Peng fell on a jump and they had unison issues with their spins.

Jin said they were quite satisfied with their performance, while Peng revealed that sickness and a leg injury had impacted their training after the Grand Prix Final.

[23] In March at the 2021 World Championships in Stockholm, Peng fell at the beginning of the short program, breaking one of the zippers on her dress, but continued the performance and put her hand down on her underrotated jump attempt.

[27] The Chinese federation opted to withdraw them from their second event, the 2021 Internationaux de France, as a result of which they could not qualify for the Grand Prix Final.

They were third in the segment despite Peng's multiple jump errors and their final lift exiting early, while the Chinese team finished in fifth place.

[30] In the free skate, Peng underrotated and stepped out of her triple Salchow attempt, but they placed sixth in the segment and remained fifth overall.

Jin said they had been under "great pressure because we had the disappointing score" at the previous Olympics and failed to qualify for the free skate but that they were pleased to have performed well in Beijing.

[33][35] The following week they competed at the 2023 Grand Prix of Espoo, where they won the short program but dropped to fourth place after the free skate.
