" Some claim Hakka as "pure" Han people. But pure Han really does not exist. Recent archaeological studies have shown that China had multiple centers of civilization, developed rather independently of each other. Yangshao ‹Âèî (Henan), Banpo ”¼š± (Shaanxi), Hongshan gŽR (Liaoning) , Liangzhu —Ç (Jiangsu/Zhejiang), Sanxingdui ŽO¯‘Í (Sichuan), Longshan —´ŽR (Shandong) all eventually merged into the Han culture.
Han people are thus the integrated composite of several different tribes. In a way, the definition of Han is just as difficult as the definition of American. Hakkas as Han cannot be ethnically pure. Hakka have been at the interface of ethnic conflicts for many dynasties. Genetically speaking, some Hakka people have clearly inherited some non-Han features such as wavy hair and high nose bridge. Hakka must have incorporated these features from the different ethnicities along the migration path through out the 2000 years of history.
The characteristic of Hakkas can only be recognized by the dialect and the adamant preservation of ancient Chinese custom."
Shortly before the organization of the Red Guard the Red Chinese hierarchy began discussing the "Period of Warring States". Then the Guard was released to kill enemies of the state.
No wonder the Chinese prefer to forget this happened!
Sometimes I think I have Hakka in me. I am Korean by the way. I like to have my genes tested.
