Liu made her
WTA Tour debut at the
2014 Shenzhen Open, having been awarded a wildcard into the main draw, but lost to
Peng Shuai in the first round. She also made her debut in
doubles, partnering
You Xiaodi. The pair lost their first-round match against
Monica Niculescu and
Klára Zakopalová, who went on to win the tournament. Six months later, Liu advanced to the final of the inaugural WTA 125
Jiangxi International Open where she again faced Peng, this time losing in a tough three-set match. Liu retired from professional tennis in November 2025.{{cite web|url=https://cn.chinadaily.com.cn/a/202512/01/WS692d10a0a310942cc49942c1.html|title=冠军花落各家，2025中国网球巡回赛建行(亚洲)香港公开赛落幕 ==WTA Challenger finals==
