The origin of Roche?

Luo, one of China's surnames, originated from the descendants of "Eight Surnames of Zhu Rong" in history books. Zhu Rong's descendants are divided into eight surnames, namely, Ji, Dong, Peng, Bald, Yi, Cao, Zhen and Mi. In 690 BC, Luoguo (Luoshan, Henan Province) was destroyed by the State of Chu, and Guo Yan (Yanling, Henan Province) was established at the original site. The descendants of Roche gradually moved south, first to Zhijiang (now in the south of Hubei Province, Zhijiang County along the Yangtze River), and then to Guluo, Hunan Province at the weekend, so they took the country name "Luo" as their surname.

During the 600 years of Song Yuanming, the net population growth rate was 20%, and the population growth rate of Luo surname was higher than that of the whole country. As the subject of Luo surname had moved from the north of the Yangtze River to the south of the Yangtze River as early as the Qin and Han Dynasties, several wars in northern China did relatively little harm to Luo surname.
