Li competed at the 2018 WOGA Classic in Frisco, Texas, placing eleventh in the all-around and winning silver on balance beam behind Japan's Ayumi Niiyama.

[2] After upgrading her difficulty value on balance beam and floor exercise during the summer and placing second in the all-around at the final internal test, Li was named to the Chinese team for the 2019 World Artistic Gymnastics Championships in Stuttgart, Germany alongside Chen Yile, Liu Tingting, Qi Qi, Tang Xijing, and alternate Zhang Jin.

[4] Individually, Li recorded the seventh highest all-around score of all competitors, but qualified into the top group of six along with teammate Liu after American Grace McCallum's exclusion due to the two-per-country rule.

In the balance beam final, she won the bronze medal behind Biles and Liu, hitting a clean routine with a few broken connections to score 14.300.

As the top 8 all-around gymnasts would be included in the training squad for the 2020 Summer Olympics this secured her a place in the team but a knee injury kept her from participating.
