Here, we share our knowledge and insights on the Chinese language and culture, as well as a few translation and localisation tips to ensure your project is a success.

Manually Proofread for Chinese Typos

The red wavy line under a typo in Microsoft Word is an iconic feature; however, it is not a functionality that is useful for Chinese users. This is because Microsoft Word and other word processing software are unable to accurately detect typing errors in Chinese. Worst yet, there is nothing commercially available that can solve this problem. The only way to ensure typos are eliminated is to proofread the Chinese document manually on a word-for-word basis.

Text Expansion and Contraction

A page of English text contracts by 25% in volume once it is translated into Chinese. Expanded or contracted text can affect the layout and appearance of your website, book, or magazine, so it is important to work with a Chinese translation agency that can assist with the formatting of your documents post-translation.

Avoid Machine Translation

At CTS, we do not recommend using machine translations on work related documents due to the high risk of mistranslation. We believe that machine translations are still unable to produce high quality translations between English and Chinese. This is despite the recent breakthroughs in artificial intelligence, machine learning, and neural networks.

Localising Culture

An effective localisation should take into account cultural preferences in colours, symbols, numbers, and societal norms and beliefs. For example, consider the phrase “Stocks are in the red, is it time to sell?”. Whilst the colour red means danger in Western society, it also represents luck in Chinese culture. A good translator will understand this and will make it clear to the reader that the stocks are falling.

Localising Numbers

Where large numbers are broken down by thousands and millions in English, the Chinese counts in a metric called Wàn which represents “ten thousand”. For example, one hundred thousand is localised as ten Wàn, and one million is localised as one hundred Wàn. As you can imagine, it is common to find conversion errors when localising numbers to Chinese.

Localising Currency

When localising your documents to Chinese, it is important to convert the currency to RMB or CNY. China’s official currency is the Renminbi (RMB), and the Chinese Yuan (CNY) is the unit of measurement. Both the Renminbi and the Yuan are often used interchangeably.

One of the most common questions we receive from clients, is whether they should translate their documents to Mandarin or Cantonese. This is technically incorrect as Mandarin and Cantonese are spoken languages. The written forms of Chinese are Simplified Chinese and Traditional Chinese.

Between 1950 to 1960, the government of China promoted the use of a simplified version of Chinese characters to boost literacy. As the name implies, Simplified Chinese is written with fewer strokes, making them easier to write compared to Traditional Chinese.

The introduction of Simplified Chinese characters faced strong resistance from the public and academics. Since then, Simplified Chinese has been officially used in Mainland China, Malaysia, and Singapore. Whereas Hong Kong, Macau, and Taiwan have continued to use Traditional Chinese characters.

Generally speaking, Chinese people can read both Simplified and Traditional Chinese. However, there are many expressions and terminologies that are used differently, so it is important to select the correct variant when translating your documents to Chinese.

Contrary to popular belief, Chinese is not a single language but instead, a group of languages spoken by the ethnic Han Chinese majority and other Chinese minority ethnic groups.

It is estimated that there are seven to thirteen major groups of Chinese languages, each of which has its own variations and dialects. Mandarin, as the official language of China, is the most widely spoken with approximately 800 million speakers. This is followed by Min, Wu (Shanghainese), and Yue (Cantonese) with 75 million, 74 million, and 68 million speakers, respectively.

  • Chinese is the most widely spoken language in the world with more than 1.3 billion speakers.
  • Chinese is one of the oldest languages in the world. Oracle bone inscriptions dated to 1250 BC are the earliest records of written Chinese.
  • Chinese became an official language of the United Nations in 1946. It is one of the six official languages, along with Arabic, English, French, Russian and Spanish.

Unsurprisingly, the biggest and most obvious difference is the appearance. Whilst English uses alphabets to help readers pronounce words, Chinese uses Hànzì which are written symbols that cannot be sounded out. Chinese characters do have components called radicals however, which can sometimes give advanced readers a rough idea of the meaning.


Chinese is a tonal language. This means that it uses pitch to distinguish word choice. In English, changes in pitch are used to emphasize or express emotion, but in Chinese, pitch represents meaning. Mandarin has four basic tones and Cantonese has nine basic tones.

Sentence Structure

It is common to use long sentences in English to express ideas since it adds flair, rhythm, and poetic power to writing. Chinese, on the other hand, does not depend on sentence structure for expression. Instead, it divides long sentences into shorter phrases separated by commas, leaving the use of Chéngyǔ (four-character idiomatic expressions) to bring life to the language.

Below are some of the most commonly searched for phrases in English and their Chinese translations.

English Simplified Chinese Translation Pinyin (Romanized Spelling)
Hello 你好 Nǐ hǎo
Thank you 谢谢 Xièxiè
Goodbye 再见 Zàijiàn
Good morning 早上好 Zǎoshang hǎo
I love you 我爱你 Wǒ ài nǐ
I miss you 我想你 Wǒ xiǎng nǐ
Good luck 祝你好运 Zhù nǐ hǎo yùn
Happy New Year 新年快乐 Xīnnián kuàilè
Happy birthday 生日快乐 Shēngrì kuàilè
Guanxi (Relationships)

A word you may often hear when doing business in China is “guanxi”. Many agree that this roughly means “relationships”, but a more literal translation is “to go through the back door”. It is an exchange of personal or business favour through relationships. Often misunderstood by Western counterparts as unethical behaviour or corruption, it is a core part of doing business in China which can often help open doors.


When it comes to doing business in China, it is important to understand the political views of the Chinese people. Whilst it is acceptable in the UK and other parts of the world to openly challenge or criticise government, the Chinese do not feel comfortable doing the same. In general, topics which are off-limits, include China’s territorial borders, Tibet and the Dalai Lama, Xinjiang, Tiananmen Square, Taiwan, Chairman Mao, and the Cultural Revolution.

Mianzi (Face)

Mianzi in Chinese culture is a metaphorical expression of preventing a loss of face. The Chinese will go through great lengths to save face, even if it means telling an outright lie, denial, or feigning ignorance. In a business setting, it is expected that both parties would be able to read between the lines instead of openly disagreeing or making criticisms.

CTS stands for Chinese translation services. We are a UK-based Chinese translation company with two decades of experience providing English and Chinese translations of documents, websites, software, and videos for private businesses and public sector organisations.

Yes. We started as specialists in Chinese translations, but we now provide translations for all the major languages, including French, Spanish, Italian, German, Russian, Japanese, Korean, and of course, Chinese!

We charge on a per-word or per-page basis because it is the fairest and most accurate way to calculate fees. After receiving and checking your documents, our team will send you an exact quote and delivery date. We’re fully transparent in our pricing, there are no surprises, and all costs are included and upfront.

The answer depends on which market the translations will be used in. If your audience is in Mainland China, Malaysia or Singapore, your documents will need to be translated into Simplified Chinese. On the other hand, if your audience is in Hong Kong, Taiwan, or Macau, your documents should be translated into Traditional Chinese.

When it comes to doing business in China, building good relationships or “guanxi” is key. Furthermore, China’s “face” culture is incredibly unique, understanding what it is and how to deal with it will greatly improve your chances of success. Additionally, the Chinese people are huge believers in creating win-win situations, so an agreement which can give both sides a win, would be extremely favourable.

Translation is the process of accurately converting written text from one language into another. Localisation is the process of adapting a translated text so that it is linguistically and culturally appropriate for its target market. Interpretation is the process of translating spoken words.

Certified translations, or ‘official’ translations are documents that have been signed, stamped, and dated by a translator to state that it is a true representation of the original text. Generally speaking, any document that is used for official purposes that is not in the language of the intended country will require a certified translation.

Before sending a document for translation, make sure that it is the final version. There have been many occasions where a client needed to revise the original document during the translation process, which caused delays to the project and increased costs. Furthermore, if you have preferred terminology or would like us to follow a glossary and style guide, please send it to us before the project begins.
