Her early content, which included gameplay and professional player analyses, quickly gained traction due to her approachable style and trilingual abilities in English, Korean, and Chinese.

Her shift to IRL streaming, featuring outdoor adventures and cultural experiences, marked her rise to prominence, especially after a 2018 fan meeting in Taiwan. Jinnytty’s career soared as she expanded her content to include global travel vlogs, earning her a dedicated international audience.
