Quick Answer
Both thế nào and như thế nào translate to "how" in English, but they are used in different contexts. Thế nào generally asks about the nature, state, quality, or an opinion on something, expecting a descriptive answer. Như thế nào, on the other hand, typically inquires about the manner, method, or process of an action, often expecting an explanation of 'the way' something is done or a comparison.

Detailed Explanation
Understanding the distinction between thế nào and như thế nào is crucial for expressing yourself accurately when asking questions in Vietnamese. While both translate to "how," their underlying meaning and expected answers differ significantly.
thế nào
Thế nào is used when you want to inquire about the nature, quality, characteristic, or general state of something. It's often equivalent to "What is X like?" or "How is X?". You are typically looking for an adjective, a description, or an opinion. It can be used after a noun or a verb (often verbs of perception or state) to ask for an evaluation or condition.
Asking for opinion/evaluation: When you want to know what someone thinks about something. Asking for status/condition: When you inquire about the current state of a person, object, or situation. Asking for characteristics: When seeking a description of something.
Consider its Hán-Việt connection: Thế (勢) can mean "situation" or "state," so thế nào fundamentally asks "what state/situation?"
như thế nào
Như thế nào is primarily used to ask about the manner, method, or process by which an action is performed. It's asking "in what way?" or "by what means?". The keyword here is như (如), which means "like" or "as." So, như thế nào literally translates to "like what (state/situation)?" or "in what manner?". You are looking for an explanation of how something is done, a process, or a comparison.
Asking for method/procedure: When you want to know the steps or means used to accomplish something. Asking for manner of action: When inquiring about how an action is carried out. Asking for comparison: Implies a comparison to a general "what way."
While sometimes native speakers might use them interchangeably in very casual speech, especially when the context makes the meaning clear, for learners, it's best to adhere to their primary functions to avoid ambiguity and sound more natural.

Common Patterns
Certain fixed patterns clearly favor one phrase over the other:
To ask for an opinion or general condition:
Noun + thế nào?
Phim này thế nào?
How is this movie? (What is it like?)
To ask how to do something (method/means):
Làm thế nào để + Verb...?
Làm thế nào để học tiếng Việt nhanh?
How to learn Vietnamese quickly?
This construction is very common when asking for instructions or methods. While "làm như thế nào" can also mean "how to do," "làm thế nào để" is a more fixed and natural phrase for seeking instructions/means to achieve a goal.
When inquiring about the manner of a specific action:
Verb + object + như thế nào?
Bạn giải thích điều này như thế nào?
How do you explain this? (In what way?)
To ask about a general process or style:
Subject + Verb + như thế nào?
Họ xây dựng cây cầu đó như thế nào?
How did they build that bridge?
Common Mistakes
Mistake 1 — Using như thế nào for general opinion/state
Learners often mistakenly use như thế nào when asking for a general opinion or the state of something, where thế nào is more appropriate.
❌ Bộ phim đó như thế nào?
✅ Bộ phim đó thế nào?
The incorrect sentence would imply "How was the movie done/made?" rather than "What is the movie like?" or "How was it?". The correct usage asks for an opinion or description of the movie's quality.
Mistake 2 — Using thế nào when inquiring about method/process
Conversely, using thế nào when specifically asking for the method or process of an action can sound unnatural or grammatically incorrect in certain contexts.
❌ Bạn làm món phở đó thế nào?
✅ Bạn làm món phở đó như thế nào?
The incorrect sentence, while understandable, sounds less precise. It's asking "What is the phở like that you made?" rather than "How did you make that phở?". The correct sentence clearly asks for the cooking method.
Mistake 3 — Misplacing the interrogative phrase
Sometimes, the placement can be off, especially with như thế nào which tends to follow the verb it modifies more closely.
❌ Như thế nào bạn học tiếng Việt?
✅ Bạn học tiếng Việt như thế nào?
The interrogative phrase usually comes after the main verb or predicate it relates to. Putting it at the beginning of a statement-like question sounds awkward. The correct sentence places "như thế nào" after the verb "học" (to learn), clearly asking about the method of learning.
