What's the difference between Liangshan Prefecture and Chuxiong Prefecture?

We use the old Yi language in Chuxiong, which belongs to the morpheme (ideographic) writing, while the Liangshan Yi language has been planned as phonography by some malicious people, and it is mostly rotated 90 degrees on the basis of the old Yi language, saying that it represents the stand-up of the Yi people. This is the result of political factors, and even the ancestors can't understand that writing, and it is extremely wonderful and ugly!
