The potential of the Chinese-speaking world is huge. It is a market that most international businesses cannot afford to ignore. Companies all over the world want to do business in these markets. Chinese is not a single market, and written Chinese varies by country and region. Considering that and the fact that it is always easier to buy in your own language, you may ask yourself which kind of Chinese script should I use?
Simplified Chinese or Traditional Chinese?
This will entirely depend on where you want to do business. Your language strategy should be market-driven, not language-driven.

• Using the wrong  variant of Chinese can confuse your audience and weaken your message. A translation in Traditional Chinese may not resonate with users in mainland China, while Simplified Chinese may not be appropriate for readers in Taiwan or Hong Kong. Choosing the script your audience expects improves clarity and trust.
• Traditional Chinese is used in Hong Kong, Taiwan, and Macau. There are two officially recognized varieties: Traditional Chinese for Hong Kong SAR and Traditional Chinese for Taiwan. The main differences are writing style and pronunciation, along with some unique characters found in one of the variants and not in the other.
  Simplified Chinese is standard in mainland China and Singapore.
  Businesses targeting these markets should adapt their content to match local preferences.
  

  2. Simplified vs. Traditional Chinese – Basic differences

  • Simplified Chinese was introduced in 1956 to increase literacy by reducing the number of strokes per character. Traditional characters retain the original, more complex forms.
  • Traditional Chinese is one of the oldest written languages. Traditional Chinese characters preserve the historical form of the writing system.
    Work with professional native linguists who specialize in technical documentation.

    3. Why script conversion is not enough

    • Vocabulary differs between regions even when both use Traditional Chinese. In Taiwan, software is 軟體 and hardware is 硬體, whereas in Hong Kong the equivalents are 軟件 and 硬件.
    • Hong Kong and Taiwan both use Traditional Chinese but diverge in terminology: Hong Kong prefers 軟件 (software) and 硬件 (hardware) while Taiwan uses 軟體/硬體; Hong Kong uses 互聯網 for “Internet” whereas Taiwan uses 網路 or 網際網路.
    • These differences extend to other UI terms such as laptop (手提電腦 vs. 筆記型電腦) and smartphone (智能手機 vs. 智慧型手機).

    4. Localization recommendations by industry

    • Industrial manufacturing: Translate product manuals, safety instructions and technical documentation into the language used by the local market.
      Use Simplified Chinese for mainland China and Singapore and Traditional Chinese for Taiwan, Hong Kong and Macau. Precision is critical because errors in technical documentation can affect safety. It is important to work with professional native linguists.
    • Software: Provide separate versions for zh‑CN, zh‑TW, and zh‑HK. Regional terminology differences mean that interface labels, error messages and help documentation must be localized, not just converted, to ensure usability. Having a good glossary for each language is of great importance, because it helps make sure the correct terminology is used.
    • E-commerce: Use Simplified Chinese for mainland China and Singapore and Traditional Chinese for Taiwan and Hong Kong. Adapt product names, payment terminology and customer service phrases to local usage. This will make readers connect with the message and may make them more willing to buy the product or service. In this case a specific glossary would help reduce possible terminological errors.

    5. SEO considerations for Chinese markets

    Baidu is the most popular search engine in China, with over 70% market share. Baidu’s algorithm prefers content in Simplified Chinese. Web pages or online content should be written or reviewed by native speakers, because machine translation is insufficient.

    6. Final recommendations for global companies

    • Think market first, script second. Conduct audience research and choose the appropriate variant for each region.
      • Separate zh-CN and zh-TW whenever possible.
      • Consider zh-HK for Hong Kong-facing products.
    • Don’t rely on automatic script conversion; adapt terminology and UI elements to local usage. Keep your glossary up to date.
    • For SEO in mainland China, publish high‑quality content in Simplified Chinese and host your site where it loads quickly for Chinese users.
    • Work with professional translators or reviewers for regulated or high‑stakes content to ensure clarity and compliance.
