She became involved in activist causes, including becoming a chairperson of Hong Kong's Association for the Advancement of Feminism, which spoke out about sexist imagery in television advertisements and hosted a mock awards night for the most sexist ads. She turned from feminist essays to cartoons when asked by an academic to produce cartoons for a gender and sexuality journal. In 1998, Lau began drawing the comic strip ''Lily's Comix,
which appeared initially in Hong Kong Film Weekly and later in mainstream newspapers like in the Hong Kong Economic Journal, The Sun, and Apple Daily''. The strip was controversial and noted for its "graphic nudity and sexual frankness". In 1998, she also publisher her first book of comics, 媽媽的抽屜在最低 - 性,性别,性别政治 (
Mom’s Drawer At the Bottom - Sex, Gender, Gender Politics). It quickly sold most of its initial 1000 copy print run and was later published in a bilingual Chinese-English version. Lau directly labels her work as feminist and Wendy Siuyi Wong and Lisa Cuklan note that "Lau deliberately engages gender politics and ideology, often by using simple observation rather than polemical argument." She has also published
This Is How Stars Should Really Be (1999), an anti-racist Chinese and English language comic book, and
The Beginning of the End (2001). In 2001, she contributed the title story to the international comics collection
Letter to a Dead Friend, a product of an art exhibition at the 2000
Fumetto International Comics Festival. == References ==
