Career In 2016, she made her WTA Tour main-draw debut at the Tianjin Open, where she was given a wildcard with Zhang Ying. The pair won their first round, defeating Han Xinyun and Zhang Kailin but then fell in the quarterfinals to second seeds Lara Arruabarrena and Oksana Kalashnikova.

She received a wildcard for the main draw of the 2024 China Open but lost to qualifier Sara Sorribes Tormo in a match that lasted for 4 hours and 15 minutes, becoming the fourth-longest match on the WTA Tour in the Open Era and surpassing the 2024 Thailand Open 2 second-round match between Laura Siegemund and Wang Xiyu in the previous week.
As the No. 1 singles player representing China at the 2025 United Cup (replacing Zheng Qinwen), Gao broke another record for the longest WTA singles match in the tournament history, when she defeated Beatriz Haddad Maia in 3 hours and 22 minutes. She subsequently defeated Laura Siegemund to send China into the quarterfinals.
