I believe it's the claim that China has 5,000 years of written history. I'm not knowledgeable on this however, so this is a vague memory semi-confirmed by a cursory internet search.

I’ve never heard a credible source state 5000 years of written history, just 5000 years of history, where the inference is that the earlier parts were orally transmitted.
