one who has a promising future
It's not a thing in the pond. It's a Chinese idiom. Pinyin means "f ē ICH í zh ō n ɡ w ù", which means it's not a small animal living in the pond for a long time. It's a metaphor for people with lofty aspirations to do great things after all. It comes from the annals of the Three Kingdoms, Wu Shu, biography of Zhou Yu.
