Human beings first lived in a matrilineal society. Chinese surnames trace their origins and are related to matrilineal society and Nuwa. The surname is a knowing character, with a female character on the left and a male character behind it. Together they mean that the surname was originally a female exclusive, so among the Chinese surnames
a number of the oldest surnames have the character "女" next to them. For example: Ji, Jiang, Ying, Si, pregnant, Huan, Juan, Yao.
Speaking of the surname Yao, we have to talk about Emperor Shun, one of the three emperors and five emperors in ancient times. Shun was the leader of the Yu tribe, so he was called Emperor Yu. The ancients often used their surnames based on their place of birth or residence. Emperor Shun got the surname Yao because he was born in Yao Xu (Heze County, Shandong Province), so his surname was Yao and Chonghua. The ancestor of the surname Yao was Emperor Shun. In addition to the surname Yao, the descendants of Emperor Shun also derived other surnames, the first of which was Gui. Gui was given to Shun by Emperor Yao, so Shun's descendants first took Gui as their surname. After the death of Emperor Shun, Dayu took over the throne. Dayu sent Emperor Shun's son Shangjun to the State of Yu (in the area of ??Yucheng County, Henan Province). The descendants of Shangjun took the name of the country as their surname. The descendants of Emperor Shun with the surname Gui multiplied from generation to generation. After a thousand years, one Guiman was born. King Wu of Zhou enfeoffed the princes and moved Guiman to Wanqiu, which is now near Huaiyang, Henan. Guiman established the Chen Kingdom here. Because of his longevity, he was posthumously named Hu Gong after his death, and Guiman was also known as Chen Hugong is full. Guiman passed on to the eleventh generation, and passed it down to the son Chen Wan. Because of the civil strife in Chen, Chen Wan fled to Qi State, and changed his surname to Tian, ??and was known as Tian Wan. After historical evolution, the surname Yao became the five surnames of Guina, namely Chen, Hu, Yao, Yu and Tian. In places where Chinese people in Hong Kong, Taiwan and Southeast Asia live together, you can often see these ancestral halls with the surname Lian Zong.
