# Vietnamese / English bilingual site

Part of the doc set: [Hưng Phát Laptop (Theme)](https://phatdev.net/en/docs/hungphat-laptop.md)

> Switch the interface between Vietnamese and English, with server-rendered (SSR) /en/ URLs that are SEO-ready and AI-translated content.

The theme supports **two languages, Vietnamese and English**. The English version lives under the **`/en/`** path and is **rendered on the server (SSR)**, so it is SEO-ready (Google can index the English version).

## Visitors switch language
Click the **VI / EN** button in the interface - the page switches to the matching version (`/en/...` for English). Content, menus, buttons and so on all change language.

## How content gets translated
- **Products and posts:** translated by **AI** (running in the background/automatically) in a native-sounding voice; products use a premium marketing tone and posts use a journalistic tone - with a faithfulness lock (no invented numbers, prices or specs).
- **Static pages** (about, policies and so on): translated carefully.
- Interface strings (buttons, labels): pre-translated inside the theme.

## What do you need to do?
Mostly **automatic**. When you add a new product or post, its English version is translated (on a schedule or when you save). If a translation needs adjusting, edit the corresponding English content.

> The English version has its own `/en/` URL so Google can index it - good for international SEO.
