China Youth Daily: Why can Microsoft be invincible in China?

Some people may think that some criticisms of Microsoft come from its competitors or those who are jealous of its success. For example, the PPT document only opens the format of some versions of Microsoft Office, not all versions. Some people tried to follow Microsoft's published binary specification document, but failed to generate a valid document. As long as the format used by Microsoft in its Office 2007 becomes one of the world standards, it can continue to monopolize.
