Gong Hakka
Read full descriptionHide full description
Gong Hakka est née d’un constat : en Polynésie française, la langue hakka des ancêtres est de moins en moins parlée par les jeunes générations, au profit du français véhiculaire. Cette désaffection croissante favorise une acculturation progressive, synonyme de perte d’identité pour la communauté. Gong Hakka vous permet ainsi de renouer avec vos origines chinoises, héritées d’une civilisation multimillénaire riche, subtile et passionnante. Grâce à l’application, vous pouvez rapidement trouver des traductions en langue hakka telle qu’elle est pratiquée à Tahiti. La recherche par mot, expression ou thème est simple et intuitive. Vous pouvez également améliorer votre compréhension orale et votre prononciation grâce aux enregistrements audio intégrés. Enfin, Gong Hakka fonctionne entièrement hors ligne : utilisez-la partout, à tout moment, sans connexion internet.
