I want to know the answer to the following question:
What may have been found at Neolithic sites in China in recent decades?
All the background I'm provided with is that "In recent decades, a series of inscribed graphs and pictures have been found at Neolithic sites in China, including Jiahu (c. 6500 BC), Dadiwan and Damaidi from the 6th millennium BC, and Banpo (5th millennium BC).". Is that enough to answer the question?
Answer: yes
