Bilingual customer communication: English and Chinese, done well.

In Hong Kong, replying in the wrong language is a small insult and a common reason for a lost enquiry. Doing it well is less about translation than about habits: knowing each customer's language, having good templates in both, and keeping the two versions in step. This guide covers the practical side, including what your software has to do.

Key takeaways

Record each customer's preferred language and use it by default.
Write templates in both languages, by people who read both, not one translated mechanically from the other.
Keep one source of truth for prices, hours and policies so versions never disagree.
Decide who answers in which language, including out of hours.
Machine translation is a drafting aid, not a finished message.

Start with the customer's choice

Ask once, remember it. A language choice at sign-up or first booking, stored with the customer record, saves guessing forever after. See CRM and customer data.
Reply in the language they wrote in if you have no record, and note it.
Allow a household to differ. A parent may prefer Chinese while the child uses English. Let the preference belong to the person, not the account.
Do not assume from a name. Neither a Chinese nor an English name tells you which language someone prefers.
Make switching easy on your website, forms and emails, and keep the choice when they move between pages.

Writing that sounds like a person

Write each version for its readers. A good Chinese message is rarely a word-for-word copy of the English; sentence length, politeness and structure differ.
Use Hong Kong Traditional Chinese with the terms local customers use, and avoid wording that reads as mainland or machine-made. Have a native reader review anything important.
Choose a tone and keep it. A booking confirmation can be warm and short. A refusal or a payment reminder needs more care. Write these templates deliberately.
Mixing is normal. Many customers move between languages in one message. Reply in the main language of the message, and keep product names and numbers exactly as written.
Names and addresses. Show a customer's name as they gave it, and do not translate it. See forms and data for Hong Kong.

What your tools need to do

Store templates in both languages, with the right one chosen automatically from the customer record.
Handle both scripts everywhere: emails, PDFs, receipts, SMS and WhatsApp. Check that characters do not turn into boxes or question marks.
Send WhatsApp messages from approved templates in the right language. Each language version needs its own approval. See WhatsApp options for business.
Keep content in one place. Prices, hours and policy text should be edited once and shown in both languages, so that nobody updates only one.
Show staff the language next to each conversation, and let them route by it.
Test long text. English can run longer than Chinese in buttons and notifications, and the reverse in some headings.

Staffing and out-of-hours replies

Know who covers which language, including on holidays and bad-weather days.
Prepare quick replies for the ten most common questions in both languages, so any staff member can answer well.
Use an automatic acknowledgement that says when you will reply, in both languages, rather than silence.
Escalate when unsure. A wrong or clumsy reply to an upset customer costs more than a short delay.

An illustration: a dental clinic

(An illustrative scenario, not a client.) A clinic records each patient's preferred language at registration. Appointment reminders go out in that language from two reviewed templates, with the time and place only, and no treatment details. The reception screen shows the language beside each patient, and quick replies exist for the common questions in both. When opening hours change, the clinic edits them once and both the website and the replies update.

Frequently asked questions

Can we use machine translation for customer messages?

As a first draft, yes. For anything customers will read as your voice, have a fluent person check it. Errors in a refund notice or a health-related message can do real damage.

Do we need to support Simplified Chinese too?

Only if you serve mainland customers who expect it. Hong Kong customers expect Traditional Chinese. Add Simplified as a separate, properly reviewed version rather than converting automatically.

What if a customer writes in a language we do not support?

Reply politely in the closest language you can, say what you can offer, and offer a call or another route. A clear, kind message beats silence.
