Does Taiwan still claim to be the legitimate government of all China? I don't think they have since the KMT lost power. You really can't make noises about 'independence' & then turn around and claim to want the whole ball of wax. But I guess if anybody could figure out a way to reconcile those seemingly opposite trends the Chinese could.
Recent analysis has demonstrated that some Chinese writing systems were developed by Mesopotamians ~ so the Chinese have returned to their digs where they know the pottery has various "symbols" to find more evidence that their current writing methods had NO Mesopotamian influence.
More recently there have been discoveries in the West (meaning Russia, Uzbekistan, etc.) where similar pottery was discovered. At the moment it is believed the symbols are not "writing" but just magic marks made by shamen.
The Chinese are attacking that idea too ~ note the reference to sentences.
Frankly, it's all nonsense. I can take my handy/dandy guide to Sioux sign language and read Shang Dynasty characters any time ~ which means, of course, that writing, and reading, are processes inherent in human consciousness. All that's needed is a set of agreed upon standards. Wouldn't be surprised to find Ice Age writing eventually.
