The inspiration of my work “ReTurn” came from a very common phenomenon of "social marginalisation” in Japan. Those elderly, childless, unemployed and unmarried people are living in cities and towns who barely contact with relatives and friends during their lifetime. Individuals who are relegating to the fringe of society, having no connections to relatives and friends, are called "social marginalisation". In contrast, Chinese society is experiencing a similar situation. Those empty-nesters who lack of emotional supports and family life struggle alone in big cities, escaping from the in-depth social connections and living in solitude. My work depicts the life trajectory of Chinese empty-nest youth, and the imagery of “fish” is emblematic of those who repel their own species. The protagonist, on one hand, is constantly withdrawing from social relationships and trying to live his life single-mindedly, on the other hand, he is facing the problem of dying alone with the aging. In my animation, the old fish is replaced by the newly born fish, and continues to live. It is a cycle from born in loneliness to dead in solitude, reflecting my interpretation of the theme of “RETURN”.
