Plants vs. Zombies 2 Garden Wars game language cannot be changed

I'm a Chinese.,Borrow my friend's account to play Garden Wars.,EA sets the language to Chinese,The download language is also Chinese Traditional.,But when you load and set up in the game, English is displayed.,How should I solve it?

There's another problem.,This game I clicked uninstall and it didn't work.,Only delete files.,But it's still stored in the computer.,How to solve it? Could it be that the English language has always been deleted because it has not been deleted?
