I've got a few chinese songs and some of them artist, album information can be displayed some cannot(just some weird characters)

why is that happening?? they all display correctly in my itunes. i have a ipod video by the way

You need to use a font that supports chinese characters.  You might also need to change the codepage.  Try some fonts out (I'm afraid I don't know which have which characters), and the manual should help you with the codepage.

Also, there is no need to shout your title.

PS. I changed the title to lowercase
