On being introduced to the painting techniques which played a key role in getting Wong Shue's work published during the 1980s, the artist's gouaches commanded the attention of numerous art collectors in different countries. Since then, although the choice of media for his work has broadened considerably over the past 25 years, the artist occasionally revisits the former use of gouache and natsume paper for some of his paintings. The River Maid series done between 2003 and 2006 are prime examples.
