Chinese phrase translation: 旱鸭子 (hàn yāzi) a landlubber

旱鸭子 (hàn yāzi) a landlubber; non-swimmer

Usage:

“旱鸭子”是指从来不下水,只在陆地上饲养的鸭子。鸭子大都可以在水里生活并且会游泳的，所以旱鸭子用来比喻不会游泳的人。
"旱鸭子(hàn yāzi)" refers to the ducks which are raised on land and never swim. Almost all the ducks can live in water and can swim, so "旱鸭子" is a metaphor for people who can’t swim.
