In the 2014-15 season, Yu/Jin made their official senior debut on the Grand Prix circuit. They won a silver medal at the 2014 Cup of China and a bronze medal at the 2014 NHK Trophy, qualifying them for their first senior Grand Prix Final in Barcelona, Spain. At the Grand Prix Final they set new personal bests in both the short program and free skate to finish in 5th place. They then went on to win their second national title. With the surprise comeback of Pang/Tong, Yu/Jin were not given a spot to compete at the Four Continents Championships in Seoul and the World Championships in Shanghai, China. Instead, they were sent to the 2015 Winter Universiade where they won the gold medal. It was later announced that they would compete at the 2015 World Junior Figure Skating Championships in Tallinn, Estonia. Despite training senior program layouts for much of the season, they managed to successfully defend their Junior World title, winning both segments of the competition.
