The term "Huaxia" was used by Confucius's contemporaries, during the Warring States era, to describe the shared ethnicity of all Chinese; Chinese people called themselves "Hua Ren". Southern Han people – such as the Hoklo, Cantonese and Hakka – all claim northern Chinese origins from ancestors who migrated from Northern China's Yellow River Valley during the 4th to 12th centuries. Hoklo clans living in southeastern coastal China, such as in Chaozhou and Quanzhou–Zhangzhou, originated from northern China's Henan province during the Tang dynasty.
