In Chinese typesetting, is there a version of Lorem Ipsum? I know relatively little about typography but I know that Lorem Ipsum or other similar bodies of text appear a lot in the world of typesetting. Because Chinese characters are pretty much square, is there a need for a Chinese Lorem Ipsum? If so, what texts or series are used?
There is no standard text, but there is sometimes the need for something equivalent (i.e. a body of text to see how typesetting looks).  Sometimes this is referred to as 乱数假文.
