Welcome to Android Central! It presumably already has Android on it, but it's almost certainly a Chinese ROM, since the device was intended for the Chinese market. You could try changing the system language to English--swipe down the notification panel, and look for the Settings icon. In the main Settings menu, scroll down until you see the Language icon (usually a big letter A). Tap that, then tap the first option, which is usually System Language. See if you can choose English there.
