# Query with Localization

Baidu results can be localized by setting the interface language used during the query.

### Parameter for Language

The SERP API provides an optional parameter to control the UI language for your Baidu search:

**`ct` (Optional):**

* `0` = **All languages** (no language restriction; default behavior)
* `1` = **Simplified Chinese** (简体中文)
* `2` = **Traditional Chinese** (繁體中文)

**Notes**

* `ct` affects the Baidu UI/interface we simulate and tends to bias snippets/results toward that script. It does **not** translate content.
* Avoid combining strict localization with domain scoping: if you use `q6` (site filter)
* Some verticals/pages may partially ignore `ct`.

### Example

To customize your SERP API request with a specific interface language, include the `ct` parameter in your GET request.

```bash
curl --location 'https://serp-api.netnut.io/search/get-html?siteType=baidu&wd=%E6%B6%88%E6%81%AF&ct=1&rawHtml=1' \
--header 'Authorization: Basic base64(username:password)'
```

**Expected Result:**

* Interface/script preference: **Simplified Chinese**.
* Results/snippets favor **简体中文** content where available.
* Baidu simulates a user searching with a **Chinese (Simplified) UI**.
