The legend of the origin of the surname Guo

originated from the surname Yi, which came from the Xia Dynasty and belonged to the country name. The ancient cold country was destroyed by Dayu when he established the Xia Dynasty. Later, Dayu sent his sons and nephews to the original cold country to cross the city, and built a surname of Guo, so the address was in Laizhou City under the jurisdiction of Yantai City, Shandong Province.

Later, because of maintaining the rule of Xia Dynasty and supporting Xia Wang's relative resistance to Han Zhuo, it was destroyed by the cold pouring of Han Zhuo, the son of Houyi, the leader of Dongyi nationality.

After the national subjugation, some people who took the name of the lost country as their surname called Guo, which is also one of the very old surnames. It is said that some of the clan members who took refuge in the clan changed their names to "Gui" and later simplified them to "Gui", all of which have been handed down from generation to generation. Everyone who has been surnamed the clan respects Dayu as the ancestor of his surname.
