how to download itnes in china?

Hello Aaronavigdor,

Thank you for using Apple Support Communities.

If you want to download iTunes in China, you can go to the iTunes page and select the download link in the options at the bottom of the page.

Apple - iTunes - 满足一切享乐所需

If you want to change to a different country, clik on the small country symbol (looks like a round button with flag colors in it) at the bottom right, and select the country you want.

Regards,
Jeff D.
