How to Say OK in Chinese: 好, 行, 可以, and 没问题

By Ray Banks·November 8, 2026·Phrases

"OK" in Chinese is 好, pronounced hǎo. It works in Beijing, Taipei, Singapore and everywhere else Mandarin is spoken, and if you learn nothing else from this post, 好 will get you through. But English "OK" is doing four different jobs (agreeing, permitting, reassuring, and just acknowledging), and Chinese has a separate word for each. 行 xíng is the Mainland's everyday "sure, that works"; 可以 kěyǐ is "that's allowed"; 没问题 méi wèntí is "no problem." And one of those four splits the strait: Mainland speakers say 行 a hundred times a day, and Taiwanese speakers almost never do.

好, 行, or 可以? The distinction that matters

Think about what the other person just did. If they made a suggestion ("let's eat at seven"), the answer is 好, "good, agreed." If they asked whether something works ("is seven OK for you?"), a Mainland speaker says 行, "that works," and a Taiwanese speaker says 可以 or 好. If they asked for permission ("can I sit here?"), the answer is 可以, "you may." And if they asked you to do something ("can you send me the file?"), the answer is 没问题 or 好的, "no problem, will do."

The three verbs are not interchangeable underneath, even when they translate to the same English word. 好 evaluates: this is good. 行 judges feasibility: this will work. 可以 grants permission or states possibility: this is allowed. You can hear the difference in their negatives. 不好 is "not good," 不行 is "won't work / not allowed," and 不可以 is a flat "you may not." Our post on yes and no in Chinese goes into why Chinese answers with these verbs rather than a single "yes."

The regional split around 行 is one of the most reliable tells in spoken Mandarin. It is not that Taiwanese speakers lack the word (行 is everywhere in compounds: 行李 luggage, 银行 bank, 不行 no way). It is that as a one-syllable "sure," it belongs to Mainland speech, and Taiwan reaches for 好 or 可以 instead. If you are learning Taiwan Mandarin, you can leave standalone 行 out of your active vocabulary entirely and lose nothing.

好的, 好啊, 好吧: the particle sets the mood

Bare 好 can sound abrupt. In real speech it almost always carries a final particle, and the particle is where the emotion lives. Get these three right and you will sound noticeably more natural than most learners.

The same particles attach to 可以 and even to OK: 可以啊 is warm, 可以吧 is grudging, OK啊 is cheerful. Once you hear 吧 as "I suppose" and 啊 as "gladly," the whole system opens up. Particles are covered properly in the Chinese grammar guide; they are the difference between sounding correct and sounding alive.

How do you say "OK, got it" in Chinese?

A large share of English "OK" is not agreement at all, just a signal that you heard. Chinese has dedicated words for that, and using 好 for all of them can make you sound like you are agreeing to things nobody asked you to agree to.

"OK" as in "I'm fine" or "either is fine"

Two more jobs English "OK" does. When someone asks 你还好吗? ("are you OK?"), the answer is 还好 hái hǎo ("I'm alright") or 没事 méi shì ("I'm fine, nothing wrong"). And when someone asks you to choose and you do not mind, you have 都可以 and, with care, 随便.

Mistakes to avoid

These are the errors that make an otherwise fluent learner sound off, ranked by how often I hear them.

• Answering every question with 好. 好 agrees to a plan. It does not answer 你是老师吗? (that needs 是) or 可以吗? (that needs 可以). If the question contained a verb, echo that verb; the yes-and-no post walks through the pattern.
• Saying 好吧 when you mean 好啊. The single most common tone error. 好吧 means "fine, I suppose." Reply to a birthday invitation with 好吧 and you have told the host you are coming under protest. If you are happy, say 好啊 or 好的.
• Using 行 in Taiwan and expecting it to sound native. It is understood, but it flags you. Say 可以 or 好. The reverse is milder: 可以 in Beijing is perfectly normal, just a shade more formal than 行.
• Treating 随便 as a polite "whatever you like." To a host it reads as indifference, to a date as a lack of effort. 都可以 or 你决定 nǐ juédìng ("you decide") does the job politely.
• Forgetting the tone change on 不. 不行 and 不可以 are said bù xíng and bù kěyǐ (a second-tone or third-tone syllable follows, so 不 stays fourth), but 不对 and 不是 are bú duì and bú shì. 不 becomes second tone only before another fourth tone. How to read pinyin covers the rule in one table.

What do 好, 行, and 可以 actually mean as characters?

All three OK-words are ordinary characters with ordinary meanings that got pressed into service as replies. Knowing the underlying meaning tells you exactly when each one fits.

好 is 女 (woman) beside 子 (child), the traditional explanation being that a mother with a child is the picture of something good. As a reply it evaluates: your plan is good, I approve. It is also the 好 in 你好 and in 好朋友, which is why it is the 24th most frequent character across the 658 graded stories in the Literate Chinese catalog (141,730 hanzi occurrences, July 2026).

行 began as a picture of a crossroads, which is why its first meaning is "to go" and why it shows up in 行人 (pedestrian) and 旅行 (travel). From "it goes" came "it works, it is feasible," and from there the reply 行, "that'll go." The same character read háng means a row or a line of business, as in 银行 (bank). Interestingly, 行 does not appear in the top 150 characters in our story corpus at all, a reminder that the reply-行 is a feature of live conversation more than of narrative prose.

可以 is 可 (permissible) plus 以 (by means of), an old two-character phrase that fused into a modal verb meaning "can, may." Because 可 is fundamentally about permission, 可以 as a reply always carries a hint of "you're allowed," which is why it answers 可以吗? so naturally. 可 ranks 33rd in our corpus and 以 47th; the compound is on almost every page. 没问题 is 没 (not have) + 问题 (problem, question), and its characters rank 49th and 69th (问) respectively.

Why Chinese has so many ways to say OK

The short answer is that Chinese does not have a word for "yes," so it never developed a single all-purpose affirmative the way English collapsed "okay" into one. Agreement is expressed by repeating or evaluating the thing proposed: the plan is 好 (good), the arrangement 行 (workable), the request 可以 (permitted), the task 没问题 (unproblematic). Each reply tells the listener not just that you agree but on what grounds, and native speakers read that information without thinking about it.

There is a social layer too. Chinese conversation tends to soften direct replies with particles, so a bare monosyllable can land as cold or clipped. 好 becomes 好的 or 好啊; 可以 becomes 可以啊. Learners who skip the particles are not making a grammar mistake, but they sound like they are reading from a form. Conversely, the terse acknowledgements (嗯, 收到) are deliberately efficient and belong to specific registers: intimacy for 嗯, the workplace for 收到. Matching the register is most of what "sounding natural" means.

See these words in real stories

Reply-words are hard to learn from lists because they only make sense next to the line they answer. These free browser stories show them in place, with tap-to-look-up on every word:

• Lil Jon Orders Coffee has 小约翰 taking his cup and replying 好的, the polite "OK, thanks" of a customer.
• Lil Jon Visits the Doctor uses 好的 as the compliant reply to a doctor's instructions, which is exactly its register.
• Dotting the Dragon's Eyes shows the negative side: 只靠一点点装饰，是不行的 ("relying on a little decoration alone won't work"), 不行 in its feasibility sense, and 可以试着 ("you could try") for possibility.

Read a few of these and 好的 will stop being a vocabulary item and start being a reflex. The full catalog is in Chinese graded readers, and the method behind it is in how to learn Chinese by reading.
