Chinese Input on T610

Can anyone help/advise how can I input Chinese char onto my T610?
I know there is a model T618 which allow chinese input but in my country does not have this model.

thanks a lot!

You need to have a Chinese version so that you can have Chinese input. You can upgrade your T610's language from English to Chinese. There are 4 versions of Chinese firmware. Hong Kong, Taiwan, China 1 and China 2!

Thanks haha298 for your help...... :)
but my hp can read chinese, only can't input it.
My hp software is R1A081 prgCXC125-581_ASIAN_LATIN_3
and R1A081 prgCXC125-562_TAE

Which file I should download for the input capaibility?
