In 2017, Hsu was part of her first Chinese musical, the Chinese version of Broadway classic Jekyll & Hyde, in which she played the role of Lucy Harris. Then, later the same year, she played the lead female role, Sara, in the Chinese version of Murder Ballad, a popular off-Broadway musical.

Hsu, who speaks many languages, including English, Dutch and Italian, improved her Mandarin while performing in Chinese musicals.

One of the Chinese musical actors she worked with was Zheng Yunlong, who has gained popularity on China's entertainment scene, thanks to the 12-episode reality show Super Vocal, produced by Hunan Satellite TV, which premiered on Nov 2.
