The dictionary says that this idiom means impenetrable defense (high city walls, deep moat). Does this mean that an individual described with this idiom is stubborn or strong in resolve?

  • For "...stubborn or strong in resolve?" try 百折不挠,(bai zhe bu nao) Jul 3, 2020 at 6:27
  • Neutral. It's not usually used to describe a person. Jul 5, 2020 at 2:48

It is a neutral term. It describes a property of an object. Not commonly used in a metaphorical sense to describe a human characteristic

高城深池 is typically used to describe a defended city, base and of course, castle.

There are many idioms graphically describe objects with no metaphorical usage.


一望無際 (cannot see the edge) describe the view of a vast area - express: vastness

皮堅肉厚 (tough skin and thick muscle) literally describes a man or an animal with tough skin and thick muscle - express: physically durable

水清山秀 (clear water and beautiful mountains) literally describes a place with clear water and beautiful mountains - express: beautiful scenery

高城深池 literally describes a castle has high wall and deep moat - express: impenetrable defense


Slightly positive, good defense is a praise for a castle.
