[Mailman-i18n] Chinese support?

Hi, I am new to mailman and to this list. I hope someone can help me. I currently have a couple of lists, majority of the members are Chinese from China. So a Chinese interface would be very helpful. mailman website states that Chinese is supported, but I cannot find information regarding to getting the files for Chinese (I am especially interested zh-CN, simplified Chinese). I am running 2.1.5 mailman (installed by the hosting company). Any help as to how I could get started would be greatly appreciated. Bin Zhang
