Cindy Ng Sio Leng was born in Macao and raised in Macao and Hong Kong. After a period of study in London in the early 1990s, she moved to Taipei in 1996 to continue her studies in contemporary ink painting where she held a solo exhibition at the Taipei Fine Art Museum. She has lived and worked in Beijing since 2008.  She moved to Shenzhen to be close to Macao in 2022.

For many years, she has attempted to liberate ink from its subservience to the brush and its long-standing purpose as vehicle for text and images. She ends the established and almost indivisible partnership between the ink and the brush, bringing ink to video, photography, paper, and oil painting. She has even experimented with new media, including interactive technologies. Her ink works cross regions and media, revealing the unique essence of ink.

Her work has been featured in solo exhibitions at Chi Ni Gallery, Taipei; Riverside Art Museum, Beijing; Orient Foundation Museum, Portugal; Galerie Ora-Ora, Hong Kong;  UNESCO Centre, Macao; Today Art Museum, Beijing; Seattle Art Museum, Seattle; Ju Ming Museum, Taiwan; Amerasia Bank Gallery, New York; The Taipa Houses – Museum, Macao; Taipei Fine Arts Museum, Taiwan.
