Li Feng
According to transmitted ancient texts, after King Wu of Zhou destroyed the Shang Dynasty in 1046 BCE, his two uncles received grants of land. One, known as the Western Guo was at Yongdi and the other, Eastern Guo, at Zhidi () (modern day Xingyang, Henan). However, this account has been questioned by modern scholars such as Li Feng, who believe that Eastern Guo was founded later by a subbranch of Western Guo.
