For years, Liang has used her art to address ecological and environmental issues. Her representative installation piece, Maasai Mara, aims to raise awareness about elephants and has been exhibited in international venues, such as the Tate Modern in London.

Ocean is the first piece in an eco-preservation trilogy Liang has been conceptualizing since completing Maasai Mara in 2018, along with the unfinished Earth and Sky.
