How to use chinese input in Linux Mint 13?

view story

http://unix.stackexchange.com – I started to use linux mint 13 mate a few days ago. What frustrates me most is that I can't found anywhere to change my input language. In windows, it is easy, just Ctrl + Shift. How can I configure the input and switch between them? Specifically I need a Chinese Traditional Input - Quick. Thanks. (HowTos)
