Tsai is generally considered easygoing and sharp. Describing herself, she says: "Most people feel I'm a good communicator, and while I wouldn't describe my personality as low-key, I don't cling to my own views; instead, I try to think of ways to resolve issues."
外界對她的評價是個性灑脫、反應靈敏，她自己則說，「一般感覺是我能溝通，我的個性不能說是隨和，但我不會堅持自己的想法，總會想辦法把事情解決。」
