The sentence attributes to Sima Qian a statement about the Erlitou culture. That cannot be correct.

Sima Qian was a Han-dynasty historian who lived in the 2nd century BCE. By contrast, "Erlitou" is a modern archaeological designation for a site/culture identified in the 20th century. The People's Government of Henan states that the Erlitou site was first discovered in 1959. Because the term and archaeological framework are modern, Sima Qian could not have written that chopsticks were used in the "earlier Erlitou culture."

At most, a modern editor could infer a possible connection between Sima Qian's discussion of early Chinese antiquity and what archaeologists now call Erlitou. But the article's wording incorrectly presents that modern inference as something Sima Qian himself wrote.

The article attributes a chopsticks passage to Confucius and calls the Book of Rites his book. That is inaccurate.

The Liji (Book of Rites) is not a book authored by Confucius. UBC Library's overview describes it as "a collection of essays on rituals and ritual principles written between the Warring States period ... to the Han Dynasty" and notes that scholars traditionally believed it was recorded and compiled by Confucius's disciples.

The chopsticks line itself appears in Qu Li I of the Liji: "If the soup be made with vegetables, chopsticks should be used; but not if there be no vegetables." In the text, this appears as a ritual rule inside the anthology, not as a quotation spoken by Confucius.

So the passage may still be evidence that chopsticks were known in early China, but calling it "Confucius' reference" in "his Book of Rites" is a misattribution.
