How to Say “To Know” in Chinese: 知道 vs 认识
There are two ways to say “to know” in Chinese: 知道 (zhī dào) and 认识 (rèn shi). But there are very important differences between the two.
There are certain circumstances where usage might be interchangeable, but more often than not you’ll want to be careful which you use. Here’s what both of them mean and when to use each one.

1. 知道 (zhī dào)
Definition: To know, to be aware of
If you are looking for a default way to say “I know…”, 知道 is usually your best bet. Its range of use and flexibility is broader than 认识. You can use it for facts, objects, or people you aren’t personally acquainted with, but are aware of or have a general understanding about.
Examples:
你怎么知道?
(nǐ zěn me zhī dào?)
How do you know?
他知道怎么样说三种语言。
(tā zhī dào zěn me yàng shuō sān zhǒng yǔ yán.)
He knows how to speak three languages.
你知道比赛的结果?
(nǐ zhī dào bǐ sài de jié guǒ?)
Do you know the result of the match?
我不知道老师的意思。
(wǒ bù zhī dào lǎo shī de yì si)
I don’t know what the teacher means.
他的目标是让人知道。
(tā de mù biāo shì ràng rén zhī dào.)
His goal is to let people know.
2. 认识 (rèn shi)
Definition: To know, understand, be familiar with, to meet (a person)
Using 认识 indicates a degree of familiarity with an object, person or idea. It implies a level of understanding that goes beyond 知道 and connotes a level of personal familiarity.
Examples:
很高兴认识你!
(hěn gāo xìng rèn shi nǐ!)
So happy to meet you!
我们是在大学认识的。
(wǒ men shì zài dàxué rèn shi de.)
We met in college.
我认识这个汉字。
(wǒ rèn shi zhè ge hàn zì.)
I know this Chinese character.
他认识到这是一件坏事。
(tā rèn shi dào zhè shì yī jiàn huài shì.)
He realized this was a bad thing.
你得认识到你的错误。
(nǐ děi rèn shi dào nǐ de cuò wù.)
You must recognize your mistakes.
When to Use 认识 vs 知道
Here are some simple tips to remember. Besides these, another tip is to use FluentU to see how to use these words in context.
- 知道 is probably your go-to when expressing “to know.” For example, if someone tells you not to be late for your appointment, you can say 我知道 (wǒ zhī dào) — “I know.”
- 知道 is for knowing of/about and 认识 is for knowing personally/being familiar with. I’ve heard of Tom Cruise, I’ve seen many of his movies, I casually follow his religious and relationship exploits online, but I have never personally met him. Thus, I 知道 Tom Cruise, but don’t 认识 him. Similarly, “我知道上海” means “I’ve heard of Shanghai.” Whereas “我认识上海” means “I’m familiar with Shanghai.” You should probably choose a friend who 认识 Shanghai to show you around.
- If you “realize or recognize something,” use 认识. If you went through the process of not knowing something to become privy to it, indicate your level of personal involvement by using 认识.
