In the work Unknown Beach Series, there are always men looking out at the ocean, seen from behind. As suggested in a Chinese idiom “Lament one's littleness before the vast ocean”, the sea horizon and the starry sky in the distance remind human beings of the limits of their sight and their life. For people who look out into it, the ocean always clears up their nostalgia for earthly life; the sea horizon is an unaltered promise to us that we will have the chance to regain a sense of loneliness. However preoccupied an ocean-observer might be, the murmurs of the ocean will smooth all wrinkles on his heart. To the ocean-observer, the sea horizon is a home and a belief. (QiuZhijie)
