Koh Min Hui was admitted into the Singapore Chinese Orchestra at the age of 21, becoming the youngest musician ever to join the orchestra. She began her professional career in 2011, shortly before graduating from the Nanyang Academy of Fine Arts (NAFA) with a Bachelor of Arts (Honours) in Music, majoring in Ruan.

An active performer and advocate of the instrument, Min Hui is the founder of the ruan ensemble acceleRUANdo, reflecting her commitment to expanding the repertoire and artistic possibilities of the instrument. Since 2020, she has been the Ruan teacher artiste of the Singapore National Youth Chinese Orchestra, and has taught at Pathlight School since 2014, where she is professionally trained to work with autistic students.

Min Hui was under the tutelage of Mdm Zhang Ronghui since 2006 and began her Zhongruan studies at the age of eight under Ms Xu Yi Ping. A recipient of the Ngee Ann Kongsi Merit Award, she graduated with Upper Second Class Honours from NAFA in 2011. A multi-award-winning musician, she became the first musician in the history of the National Chinese Music Competition (now known as the Singapore Chinese Music Competition) to clinch First Prize in the Zhongruan Open Category in 2008. She was also the only Gold Award recipient representing Singapore at the 2010 Inaugural International Ruan Competition (Professional Youth Category), organised by the China Nationalities Orchestra Society in Beijing.
