Gemini’s Traditional Chinese ability is already mature in 2026, and everyday use is almost frictionless. Back in early 2025, its reply quality clearly lagged behind ChatGPT. By 2026, that gap has narrowed enough that you usually don’t feel it in normal use.
For Traditional Chinese users, the key question is not whether Gemini can speak Chinese. It comes down to three more practical things: how to make it consistently use Taiwan Traditional Chinese, how to write Chinese prompts that get the best results, and whether long-form writing should be handed to Gemini at all.
Basic setup: make Gemini speak Traditional Chinese
Open gemini.google.com, and you can switch the language from the top-right corner. After setting it to Traditional Chinese, the interface and default reply language both switch to Traditional Chinese.
Changing only the interface language isn’t enough. Gemini can still reply with Simplified Chinese-style wording sometimes, especially on technical topics.
The practical approach is to set the preference in the first message:
“Please reply in Taiwan Traditional Chinese, and use wording common in Taiwan.”
After adding this sentence, the chance of seeing Simplified Chinese-style terms such as “用戶”, “優化”, and “程序” drops a lot.
If you use Gemini’s Custom Instructions feature, you can write this preference there so you don’t have to repeat it in every conversation.
Gemini Live now officially supports Traditional Chinese too. You can speak Chinese to Gemini by voice, and it will reply with Chinese voice output. It can also integrate with services such as Google Calendar, Tasks, and Keep. For people who are used to voice interaction, this update makes Gemini much more practical for Chinese users.
How to write Chinese prompts
Speaking Chinese to AI isn’t just typing whatever comes to mind. It works, but the gap between a good prompt and a sloppy prompt is huge. For a full prompt-writing walkthrough, read Prompt Engineering Guide and Advanced Prompt Tips.
Concrete beats abstract
Bad prompt: “Help me write an article about AI.”
When Gemini gets this kind of instruction, it tends to return a long, generic piece that skims everything and goes deep on nothing.
Good prompt: “Write a 200-word paragraph introducing Gemini’s Deep Research feature. The target reader is a Taiwan user who has never heard of this feature. Keep the tone friendly but not childish.”
Once the word count, topic, audience, and tone are all specified, Gemini’s reply quality improves a lot.
Give examples
This works for every AI model. Give it a short sample in a writing style you like, then ask it to follow that style. The result is much better than describing the style with a pile of adjectives.
“Here is an example of the writing style I like: [paste a paragraph you wrote]. Please use a similar tone and structure to write an introduction to Gemini’s Chinese ability.”
Give instructions step by step
If you throw too many requirements in at once, Gemini can easily miss something. Break a large task into smaller steps, confirm each step, then move on.
Step 1: “First, list five aspects of Gemini’s Chinese ability.” Step 2: “Expand the second point, long-form writing, into a 300-word paragraph.” Step 3: “Make the tone a little more conversational, like talking to a friend.”
Chinese-specific notes
Avoid language that is too classical: If you write something like “please expound upon the merits and deficiencies of this function,” Gemini may answer in a stiff classical style. Use normal written Chinese instead: “What is good about this feature, and what are its drawbacks?”
Technical prompts can mix Chinese and English: A common pattern is: “Use Python to write a function. The input is a list of strings, the output is a deduplicated list, and please add Chinese comments.” Gemini understands this kind of mixed Chinese-English prompt well. Keeping programming terms in English usually produces better code than describing everything in Chinese.
Reply quality tests
Chinese reply quality across common scenarios:
Everyday chat
For local recommendations, restaurants, and daily-life Q&A, Gemini’s wording is natural and the structure is clear. Specific recommendation details, such as whether a store is still open or its business hours, may not be current, so you still need to verify those yourself.
Translation
Short English-to-Chinese and Chinese-to-English passages are very usable. The wording is generally smooth, and most proper nouns are translated correctly. It sometimes leans toward Simplified Chinese-style terms, such as “信息” instead of “資訊”, but that usually doesn’t affect comprehension.
Long-form writing
This is the weakest part of Gemini’s Chinese. The articles it produces have complete structure and accurate information, but they read like reports. Sentence length is too even, the tone is too neutral, and it lacks personal voice. If you want warm long-form writing, Claude’s Chinese performance is a better fit, and Claude vs ChatGPT has a fuller comparison.
AI background removal
Using Chinese instructions to ask Gemini for background removal is very efficient, and the results are good. The key is to clearly say what to keep and what to remove. Otherwise, it may accidentally damage parts of the image you wanted to preserve.
Code with Chinese comments
The code itself is fine, and the Chinese comments are clear. Simplified Chinese-style wording may occasionally appear in comments, but it doesn’t affect practical use.
Comparison with ChatGPT’s Chinese
This is the question Taiwan users ask most often.
Everyday chat: tie. Both have reached usable Traditional Chinese quality, and it’s hard to say one is clearly better.
Long-form writing: ChatGPT wins. ChatGPT’s Chinese articles read more naturally and have better rhythm. Gemini’s long-form writing is drier and more report-like. Both are still behind Claude.
Translation: Gemini wins by a little. Gemini’s translated sentences are a bit smoother than ChatGPT’s, especially for English-to-Chinese.
Technical content: Gemini wins by a little. Its structure is clearer, and its step-by-step breakdowns are more complete, possibly because of Google’s training data around technical documentation.
Traditional/Simplified mixing: both have this issue, about equally. Both need “Taiwan Traditional Chinese” specified in the prompt to keep it down.
Overall, if you only pick one, either works for everyday use. Gemini’s advantage is Google ecosystem integration, while ChatGPT’s advantage is long-form writing quality. For the full comparison, read Gemini vs ChatGPT.
Common questions from Taiwan users
Can I use Gemini in Taiwan?
Yes. gemini.google.com is directly accessible in Taiwan and doesn’t require a VPN. Sign in with a Google account, and you can use the free version.
How do I subscribe to a paid plan in Taiwan?
Click upgrade directly inside the Gemini interface, and you can pay with a Taiwan credit card. Billing will be in NT dollars. For plan details, see Gemini Free vs Google AI Pro.
Will Gemini use my conversations for training?
Google’s privacy policy explains this. Conversations on the free version may be used to improve the service. Paid plans have stricter data protection. If this matters to you, read Google’s latest privacy terms, because data usage policies differ by plan.
Why does Gemini sometimes reply in English?
Usually because the question contains a lot of English, so Gemini “assumes” you want an English reply. Add “Please reply in Traditional Chinese” at the end of the prompt. Set it once in Custom Instructions, and you won’t need to add it every time.
Can Gemini process Chinese PDFs?
Yes. After uploading a Chinese PDF, you can ask questions about the document content in Chinese. The Pro model understands documents better than Flash, so for important files, I recommend switching to Pro.

Penchan’s experience
I usually use AI tools entirely in Traditional Chinese. Since the content I make is for Chinese readers, writing Chinese articles with Chinese prompts avoids translation hops and is the most efficient workflow. Gemini’s Chinese ability really has matured a lot by 2026. Everyday Q&A, translation, and image generation all run fine.
I still don’t hand long-form writing to Gemini. Claude remains my main tool there, because the gap in tone and rhythm for long Chinese writing is real.
To be fair, Gemini also has annoying moments: it has more restrictions, and sometimes it throws back “this can’t be done” or “that isn’t possible” replies, so you need to work around it with prompts. Chinese image prompts also get rejected more often than English ones. But AI background removal with Chinese instructions is genuinely smooth, and Gemini does well here; the trick is keeping instructions clear so it doesn’t accidentally clip other elements.
Overall, Gemini is irreplaceable for Google ecosystem work and image workflows, but for everyday chatting, long-form writing, and rule-heavy work, I still switch to Claude.

FAQ
Q: Does Gemini support Traditional Chinese?
Yes. You can talk to Gemini in Traditional Chinese, and it will reply in Traditional Chinese. The interface language can also be set to Traditional Chinese. It sometimes mixes in Simplified Chinese wording, but overall quality is above average among mainstream AI tools.
Q: How should I write Chinese prompts for Gemini?
The logic is the same as English prompting: be concrete, structured, and give examples. The extra Chinese-specific trick is to avoid extremes that are too classical or too casual. Normal written Chinese works best. If the reply leans Simplified Chinese, add: “Please reply in Taiwan Traditional Chinese.”
Q: Which is better for Chinese, Gemini or ChatGPT?
Each has strengths. ChatGPT writes long Chinese articles more naturally, while Gemini is more convenient for Google ecosystem integration and information lookup. Everyday chat quality is similar, so choose based on the use case.
Q: Does Gemini mix up Traditional Chinese and Simplified Chinese?
Sometimes. The most common issue is Simplified Chinese-style wording appearing in replies, such as “用戶” where Taiwan usage more often says “使用者”, or “優化” where Taiwan usage often says “最佳化”. Specifying “Taiwan Traditional Chinese” in the prompt helps.
Q: Do English prompts work better than Chinese prompts?
It depends on the task. Code generation and technical documentation do tend to work better in English, which is true across AI models. For everyday chat, translation, and Chinese writing, Chinese prompts are fine. You don’t need to force everything into English.
Q: Can Gemini translate Chinese?
Yes, and the quality is decent. It supports Chinese-to-English and English-to-Chinese translation, and short paragraphs are generally usable. Long-form translation can occasionally sound awkward, but it is more than enough for quickly understanding the gist of an English article.
