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

Proofread Documents for Typos

The spell-check function in Microsoft Word is one of its most widely used features. However, it is not available in the Chinese language. In fact, out of the 93 languages that Microsoft currently supports, only Chinese and Japanese do not have spell-check functionality. If you are interested in understanding why spell checkers do not work for these two languages, including the steps we take to eliminate typos in our translations, reach out to us, and we’ll explain everything to you in detail.


Text Expansion and Contraction

When a document in English is translated into Chinese, it contracts up to 33% in volume. This is something to keep in mind if the translated material is a website, book, or magazine. It is helpful to work with a translation company that offers desktop publishing services, as they can assist with the layout and presentation of your documents post-translation.


Avoid Machine Translation

Machine translations should only be used when a rough understanding of the material is sufficient or for entertainment purposes. We do not recommend using it on work-related documents due to the high risk of mistranslation.

Localization is the process of adapting translated text so that it is linguistically and culturally appropriate for its target market.


Localizing Culture

Localization takes into account cultural preferences in colors, symbols, numbers, and societal norms and beliefs. For example, while red represents danger in Western societies, it also represents luck in Chinese culture. An excellent example is the stock symbol (ticker) often used by stock traders, where red represents falling stock prices in the USA but indicates increasing stock prices in China.


Localizing Numbers

Large numbers in Chinese are counted in units of ten thousand called Wàn (Maan6 in Cantonese). For example, one hundred thousand is localized as ten Wàn (ten sets of ten thousand). From our experience, incorrect localization of numbers is one of the most common Chinese translation errors.


Localizing Dates and Currency

The official formatting of dates in Mainland China is YYYY/MM/DD, and the official currency is the Renminbi (RMB) or Chinese Yuan (CNY). In Hong Kong, the official formatting of dates is DD/MM/YYYY or MM/DD/YYYY, and the official currency is the Hong Kong Dollar (HKD).

When clients reach out to us, we often hear “Mandarin” and “Cantonese” used instead of “Simplified Chinese” and “Traditional Chinese.” Here, we’ll give a brief overview of when they should be used.


Mandarin and Cantonese are spoken languages. Mandarin is spoken in Mainland China, Taiwan, and Singapore, whereas Cantonese is spoken in Hong Kong and Macau.


Simplified Chinese and Traditional Chinese, on the other hand, are written languages. Chinese natives in Mainland China, Singapore, and Malaysia read and write in Simplified Chinese, and locals in Hong Kong, Taiwan, and Macau read and write using Traditional Chinese. Generally speaking, readers of Traditional Chinese may be able to read Simplified Chinese, but not the other way around.


In the context of our services, Mandarin and Cantonese (spoken languages) are the correct words to use when referring to interpreting services. On the other hand, Simplified Chinese and Traditional Chinese (written languages) should be used when referring to document translations.

You may be surprised to learn that Chinese is not a single language but a group of languages spoken by 56 ethnic groups in China. It is not exactly clear how many Chinese languages there are, with the latest estimates at approximately 300 variations and sub-dialects.

Officially, there are ten main groups of the Chinese language. Mandarin is the official language of China, and it is spoken by more than 800 million people. The nine remaining varieties include Yue (84 million), Wu (77 million), Min (60 million), Jin (45 million), Xiang (36 million), Hakka (34 million), Gan (31 million), Hui (3.2 million), and Ping (2 million).

  • With more than 1.3 billion speakers, Chinese is the most widely spoken language in the world.
  • 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.

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

Guānxi (Relationships)

Guanxi refers to an individual’s connections and involves mutually beneficial personal and business relationships. Strong guanxi in China can benefit you on many levels, for example, winning a contract with a client or getting priority for surgery. It is a core aspect of Chinese culture and, therefore, critical to doing business in China.

Political landscape

While it is acceptable for Americans to challenge or criticize their government publicly, the Chinese do not feel comfortable doing the same. Off-limits topics generally include China’s territorial borders, Tiananmen Square, Taiwan, Chairman Mao, the Cultural Revolution, Tibet, the Dalai Lama, and Xinjiang.

Miànzi (Face)

Face is a sociological concept observed in many cultures. In China, Mianzi plays a vital role in society. The Chinese will go to great lengths to give and save face, and misunderstanding can have serious consequences for an individual or a business. Fundamentally, giving face is an act that shows respect, and conversely, not giving face can be seen as showing disrespect.

Understanding Chinese culture is essential to building successful relationships in China.

Guanxi is a crucial component of Chinese business culture that, when done correctly, can open doors for you and your business.

Due to the high risk of mistranslation, we do not recommend using machine translations unless you only require a rough understanding of the document or when the translation is for entertainment purposes, anything that is not mission-critical.

An English translation is required if you submit a foreign language document to USCIS. Furthermore, the translator must sign a certification that they are competent to translate the foreign language document into English and that the translation is complete and accurate.

If you are ordering a certified translation, please ensure that all the details on the original document are correct. We are required to translate the documents exactly as it is, even if the original text is “wrong.”
