Rachel Cheung was born and is based in Hong Kong. After graduating from the Bachelor of Arts (Fine Art) programme jointly presented by RMIT University and Hong Kong Art School in 2001, with a major in ceramics, she obtained a Master degree in Fine Arts (Glass) from the University of Sunderland and another Master degree in Fine Art from the Middlesex University in the UK. Her artworks are collected by Hong Kong Museum of Art, Hong Kong Heritage Museum and Taiwan Yingge Ceramics Museum.

Rachel was a winner of the ‘Hong Kong Art Biennial Exhibition 2001’. In 2002, she won the ‘Artists in the Neighbourhood Scheme II’ award. Rachel was invited to participate in the International Biennale of Contemporary Ceramics 2006 in Vallauris, France; and the Setouchi Triennale 2016, Japan, Fukutake House Project.

Through the interplay between ceramics and different materials for years, as well as in recently years through community projects, Rachel’s art practice focuses on the exploration of "equilibrium" and "relationship". She believes that the state of equilibrium among relationships can be interpreted from various perspectives, including physical, philosophical and spiritual ones. Equilibrium is also in close connection with changes among relationships. Changes give rise to subtle transformation, different forms of energy, and the formation of new relationships, which then lead to other prominent impacts.

張煒詩作品藉著陶瓷和不同物料探討「平衡」和「關係」。她認為平衡關係的意義涵蓋物理、哲學及精神性。平衡是關於關係和改變，新的關係影響深遠，創造引領出更美好的未來故事。
