Of Franco-Vietnamese origin, Hélène Phung participated from a very young age, from the late 1970s to the 1980s, in numerous underground poetry movements, primarily in France, but also in Belgium. Publishing under the name Hélène Serpollier, she published various pamphlets and collections with Castor Astral, Le Crayon Noir, Polder, etc., and contributed to journals such as Ecriterre, Les Ateliers de l'agneau, Contreciel, etc. A literary and personal rupture brought an end to all written production for about thirty years.
