* Region-Specific Games: Some PS Vita games were released specifically in Chinese-speaking regions (China, Hong Kong, Taiwan, etc.). These games are often designed with Chinese text and voice acting, which is why you're seeing them in that language.
* Game Language Settings: The language displayed on a game can be changed in the PS Vita system settings. You may have inadvertently changed the language to Chinese, or the previous owner of your Vita may have set the language to Chinese.
* Physical Copies: If you purchased a physical copy of a game from a Chinese retailer or online store, it's likely the game is intended for the Chinese market and therefore in Chinese.
How to Change the Language:
1. Access the PS Vita Settings: From the PS Vita home screen, navigate to the "Settings" menu.
2. Find Language Settings: Look for the "Language" option within the settings menu.
3. Select Your Preferred Language: Choose your preferred language from the list of available options.
If the game itself doesn't offer language options, you might need to find a different version of the game that is in your desired language.
