Tseng was born in 1993 or 1994 in the
Tamsui District of
New Taipei City, Taiwan, to a Taiwanese father and
Hunanese mother. She began practicing martial arts at a young age due to the influence of her grandfather, including learning
Northern Praying Mantis and
nunchucks. She split her childhood time between Taiwan and China, Tseng continued her studies at the
USC School of Dramatic Arts in 2013 and graduated with a
Bachelor of Arts in theater. From 2017 to 2019, she starred in
David Henry Hwang's play
Chinglish on the invitation of a friend, which sparked her interest in acting. Instead of returning to Taiwan to start a cafe in
Taitung City as initially planned, she enrolled at USC again to pursue a
Master of Fine Arts in acting and intended to pursue a career in stage performances. However, Tseng deferred her studies for a year in 2021 due to
COVID-19; she ultimately quit the program in her second year when she was cast in
3 Body Problem. == Career ==
