Many Chinese learners know that 赶紧, 赶快, 赶忙, and 连忙 can all mean something like “quickly,” “hurry up,” or “immediately.”
But they are not exactly the same.
Some are used to urge someone to do something quickly.
Some are used to describe a quick reaction after something happens.
If you use them in the wrong place, the sentence may still be understandable, but it can sound unnatural.
Let’s look at them one by one. 🌿
1. Part of Speech
赶紧 gǎnjǐn
赶快 gǎnkuài
赶忙 gǎnmáng

These four words are usually used as adverbs.
They are placed before a verb or verb phrase.
Basic structure:
Subject + 赶紧 / 赶快 / 赶忙 / 连忙 + Verb
For example:

2. 赶紧: Hurry Up and Do It Now

3. 赶快: Quickly / As Soon As Possible
赶快 is very close to 赶紧.
It also means “quickly” or “hurry up.”
It can be used to urge someone to do something soon.
Compared with 赶紧, 赶快 sounds a little more neutral and slightly more formal. It is also common in both spoken and written Chinese.

Example 2

4. 赶紧 vs 赶快
In many sentences, 赶紧 and 赶快 can be exchanged.
Both are natural:
你赶紧走吧。
Hurry and go.
你赶快走吧。
Go quickly.

The difference is small:
赶紧 sounds more spoken and urgent.
赶快 sounds more neutral and sometimes a little more formal.
For daily conversation, 赶紧 is very natural.
For instructions, notices, or slightly formal situations, 赶快 can be suitable.
5. 赶忙: Hurriedly Did Something
赶忙 means “hurriedly” or “quickly.”
But it is usually used to describe that someone quickly did something after noticing a situation.
It often appears in storytelling or written Chinese.
Example 1

Key feeling:
赶忙 describes a quick action in response to a situation. It often sounds a little more narrative.
6. 连忙: Immediately in Response
连忙 also means “quickly” or “immediately.”
It strongly suggests that someone reacts right after something happens.
It is very common in stories and descriptions.
Example 1
孩子哭了,妈妈连忙抱起他。
The child cried, and the mother immediately picked him up.
Example 2
我说错了话,连忙向她道歉。

Example 3

After hearing the news, he immediately opened his phone to check.

Key feeling:

7. 赶忙 vs 连忙
赶忙 and 连忙 are often very close.
Both can describe a quick reaction after something happens.
For example:
听到老师的问题,他赶忙回答。
Hearing the teacher’s question, he hurriedly answered.
听到老师的问题,他连忙回答。
Hearing the teacher’s question, he immediately answered.

Both are correct.
The small difference is:
赶忙 emphasizes “hurriedly doing the action.”
连忙 emphasizes “immediately reacting to the situation.”
In many daily situations, they can be used almost the same way.
8. The Most Important Difference
The biggest difference is between these two groups:
赶紧 / 赶快
These can be used to urge someone to do something quickly.
赶忙 / 连忙
These usually describe someone quickly reacting after something happens.
Compare:
你赶紧回家吧。
Hurry and go home.
你赶快回家吧。
Go home quickly.
These are natural because the speaker is urging someone.
But these are not natural as commands:
你赶忙回家吧。
你连忙回家吧。
Why? Because 赶忙 and 连忙 usually describe a reaction, not a direct command.
Better:
听到孩子生病了,他连忙回家。
After hearing that the child was sick, he immediately went home.
发现天快黑了,他赶忙回家。
After noticing that it was getting dark, he hurried home.

9. Common Mistakes
Mistake 1: Using 连忙 as a command
Incorrect:
你连忙去医院吧。
This sounds unnatural because 连忙 is usually not used to tell someone what to do.
Better:
你赶紧去医院吧。
Go to the hospital quickly.
Or:
你赶快去医院吧。
Go to the hospital as soon as possible.
Mistake 2: Using 赶忙 for a general habit
Incorrect:
我每天赶忙学习中文。
This sounds strange because 赶忙 usually describes one quick reaction, not a daily habit.
Better:
我每天都努力学习中文。
I study Chinese hard every day.
Or:
我每天都尽量抽时间学习中文。
I try to make time to study Chinese every day.
Mistake 3: Thinking all four words are always interchangeable
Sometimes they are close, but not always.
Natural:
老师来了,我们赶紧坐好。
The teacher came, and we quickly sat properly.
Natural:
老师来了,我们连忙坐好。
The teacher came, and we immediately sat properly.
Both work here because there is a clear situation: the teacher came.
But for urging someone, only 赶紧 / 赶快 are natural:
你赶紧坐好。
Sit properly quickly.
你赶快坐好。
Sit properly quickly.
