Tang won the gold medal as part of the Chinese team with He Licheng, Qi Qi, Yin Sisi, and Zhao Shiting at the 2018 Asian Junior Championships in Jakarta, Indonesia. Individually, she won the gold on balance beam ahead of Yin and Eum Doh-yun of South Korea. Tang won the bronze medal in the all-around at the 2018 Chinese National Championships behind Luo Huan and Zhang Jin. She won silver with the Beijing team and placed fourth in the uneven bars final.
Tang was named to the Chinese team for the 2019 World Championships in Stuttgart, Germany, alongside Chen Yile, Li Shijia, Liu Tingting, Qi Qi, and Zhang Jin.[4] She helped the team qualify in second behind the United States and was the first reserve on uneven bars.[5] Tang failed to qualify to the all-around final due to the two-per-country rule. She competed on vault, where she debuted a new double-twisting Yurchenko vault, uneven bars, and floor during the team final to help China place fourth behind the United States, Russia, and Italy after the team counted three falls.[6]
Tang replaced Liu in the all-around final after Liu's withdrawal.[7] Despite qualifying in 21st place to the all-around, since she was replacing sixth-place qualifier Liu, she was seeded in the top rotating group. Tang hit four strong routines to win a surprise silver medal in the all-around behind five-time world champion Simone Biles of the United States and ahead of 2019 European Games Champion Angelina Melnikova of Russia. She recorded the second-highest beam score of the day behind Biles. This finish marks the highest placement of a female Chinese gymnast in World Championships or Olympic history, matching Jiang Yuyuan's second-place finish at the 2010 World Championships. It was also the first all-around medal won by a Chinese woman at the World or Olympic level since Yao Jinnan's bronze medal at the 2011 World Championships.[8]
2020
After the postponement of the 2020 Summer Olympics due to the COVID-19 pandemic, Tang competed at the delayed Chinese National Championships in September.[9] As the reigning World all-around silver medalist, Tang was a favorite for the title.[10] In the qualification round, which also served as the team final, Tang and Qi Qi led the Beijing provincial team to a fourth consecutive silver medal. Individually, a major error on uneven bars and a fall on balance beam caused Tang to miss qualifying for both of those event finals and to enter the all-around final in sixth place.[11] However, a strong performance on floor featuring a new full-twisting double tuck allowed her to qualify to that final in third place behind Qi and reigning national champion Shang Chunsong.[11] After qualifications, Tang said she felt physically stronger and that she hoped to overcome her pattern of making errors in the first round of a competition.[12][13]
In the all-around final, Tang improved on her qualifications performance to place fifth in the two-day combined all-around standings. Tang recorded the top beam score of the day by a wide margin after landing her new double pike dismount and earned the fourth-highest score on both vault and floor exercise. Another major error on the uneven bars prevented her from making the all-around podium, with her training mates Wei Xiaoyuan and Qi Qi ultimately taking silver and bronze.[14][15] In the floor exercise final, Tang also placed fifth with a clean routine, less than a tenth from the podium.[16]
