1. New file: Add a new JSON file in the [frontend/src/langs](../frontend/src/langs/), with the file naming format is "
{language}-{region}.json", e.g. English is "en-us.json", simplified Chinese is "zh-cn.json". Highly recommended to duplicate the [en-us.json](../frontend/src/langs/en-us.json) file and rename it.
2. Fill content: Refer to [en-us.json](../frontend/src/langs/en-us.json), or duplicate the file and modify the language content.
3. Update codes: Edit[frontend/src/langs/index.js](.../frontend/src/langs/index.js), import the new language data inside.
```javascript
import en from './en-us'
// import your new localize file 'zh-cn' here
import zh from './zh-cn'
export const lang = {
en,
// export new language data 'zh' here
zh,
}
```
