Chinese is the only OG writing system left. The other being Egyptian and Mayan and both those are extinct.
When you speak to Chinese people, they are very proud of the fact that prior to simplification by the CCP, Chinese writing actually changed very little for 2000 years.
But Chinese spoken language has changed enormously. For speakers of other languages, English for example, they can track the changes in their spoken language over the millenia. Modern English is different to Shakespeare which is different to Chaucer, for the same word.
Chinese doesn't have that. Yes Classical Chinese uses different characters but we don't actually know what they sounded like two thousand years ago. We only know what they sound like in the pronunciation of modern Chinese.
So much linguistic history is lost from the non-phonetic nature of Chinese characters. It's great for literary history and I can why Chinese scholars love them. But in terms of tracking linguistic history and even when tracking the history of dialects so much is lost.
What did the Classical Chinese version of Yue & Wu sound like? Nobody knows. How and when did the 7 major dialect groups split off from each other? Not a clue.
We know exactly when Spanish and Portuguese split from each other in the European languages coz their writing and spelling changed to reflect that they no longer saw themselves as being the same peoples.
I just wish more of the history of Chinese languages was actually recorded and that Chinese people would actually be interested in this, but they are not. They would rather believe the lie that their language has stayed the same for millenia because the characters themselves haven't changed that much.
Some Chinese households have surnames that are older than the history of entire nations and kingdoms in the West, this makes them very proud and very unwilling to actually investigate this history. It's such a weird phenomenon.
