The first Chinese history wasn't written down until around 100BC (https://en.wikipedia.org/wiki/Records_of_the_Grand_Historian https://en.wikipedia.org/wiki/Records_of_the_Grand_Historian) and only covered as far back as the Yellow Emperor (2698BC to 2598BC), and the first Chinese writing (https://en.wikipedia.org/wiki/Oracle_bone_script https://en.wikipedia.org/wiki/Oracle_bone_script) didn't appear until about 1250BC, so we're entirely reliant on archaeology for the period in question.
