Query: A Big Mistake in the Book--what's an oracle bone

The oracle bone and the bones of Peking men are not the same. The former was locater in Anyang, Hunan Province, and the later was discovered in Zhoukoudian, as the book calls, the Mouth of the Mountain. It's a pity that Amy Tan made such a big mistake in her fourth book.
