When I was young, the Russian writer Gorky's works “Petrel” is my understanding of the sea all, Its metaphorical, symbolic and political meanings have faded today, but the vast sea, the wind, the dark clouds and the petrels like black lightning are still my memories of the sea. The "Yan" series are shoot in the sky, through cabin window, the difference between ever-changing sky and ocean are blur. And it is this illusion that creates another kind of metaphor and anxiety. At some point in the future, can we only replace the real seascape with this illusion?
