How to open the file ending with djvu?

I download some files which extension name is djvu. I have no ideal how to open it or which program can read this kind of file.

Through Google, Wikipedia, some information retrived.

DjVu is a computer file format designed primarily to store scanned documents, especially those containing a combination of text, line drawings, indexed color images, and photographs.

Here is a site to contain helpful resources and links. http://djvu.org/resources/

I downloaded the desktop program WinDjView and installed it on my Windows 7.

The file I open in it is a Chinese Ebook. The Characters are displayed correctly.

To download the WinDjView WinDjView-2.0.2-Setup.exe
