The air by the sea always carries a faint fishy smell.
Tips
usage
腥 (xīng) is the specific adjective for the smell of raw fish, seafood, or blood — distinct from generic 'stinky' (臭 chòu). To say something smells fishy, use 有腥味 or the verb-attribute 腥. Cooks 'remove the 腥味' with ginger and rice wine: 去腥 (qùxīng).
