Sắc Nước Hương Trời: Mai San

Lotus Gallery shows work by painter Mai San from the 1960s to the 1990s, mostly ink and gouache on paper. Quick drying and suited to sketching on the spot, the medium let her catch passing moments on her travels: upland villages, markets, river landings and festivals, set down in flat, decisive blocks of vermilion, indigo, green and bright yellow. Open daily 9am to 6pm until November 1, free entry.
