In ancient Chinese there is a saying that loosely translated, goes "When the sea dries and the rocks crumble" emphasizing the everlasting nature of things. Wu T'ai, a small village in southern Taiwan has, because of it's underlying geological structure, an abundance of a black stone called "nien ban yan."
世人常以「海枯石爛」來形容永不改變，「海」與「石」的「穩定性」可見一斑。
