In September, Liu was named to the nominative roster for the Chinese team for the 2017 World Championships to compete the all-around alongside Luo Huan, with specialists Wang Yan and Fan Yilin rounding out the team. Shortly after, Liu competed as a member of the Guangdong provincial team at the 2017 National Games. She upgraded to a double-twisting Yurchenko vault for the first time since the 2016 National Championships and contributed performances on all four events in the team final to the gold medal. In the all-around final, Liu recorded the top score on beam and won the silver medal behind junior provincial teammate Chen Yile and ahead of Wang and Luo. In event finals, she placed eighth on bars, fourth on beam behind juniors Li Qi, Chen, and Tang Xijing, and third on floor behind Wang and Chen.
