The default Magento only has the English language pack, so if you want to also display Chinese, you will need to install the Chinese language pack.
Steps:
1. First, go to http://www.magentocommerce.com/langs/list/download Chinese package extract to Magento directory, it copied to two directories: one is app\design\frontend\default\ Default\locale, the other is App\locale.
2. Go to System--configuration, then the upper left corner of the current Configuration scope drop-down box, you can see the default Config->main website->main Website Store->default Store View.
3. Now go to system->manage Stores and create a new store View:
Store:main Store
Name: Chinese
Code:chinese
Status:enabled
Sort order:0
4. Store back to System > Configuration. In the current Configuration scope drop-down box, now see Chinese store view, click:
In the Locale Options tab, remove the selection of the "Use website" check box and change its locale to Chinese (China). Save.
OK, now you have the Chinese shop.
5, another way is to put the next language pack directly into the app/local/directory, and then register
