If anything there are several Y chromosome clusters in China.
No they didn't,only the elite of Minyue had descended from Goujian while Nanyue elites were hybrid Yue and Qin Chinese.
Minyue/Dongou natives were forced to move in between the Huai and Chang Jiang not the other way around,everyone here is sick of your blatant distortions.
You haven't answered my question are Kinh Vietnamese with Cham or Khmer blood not true Vietnamese?
From this graph we can see that the division of Southern/Northern Han is too simplistic according to 基於STR 基因頻率探究我國32 個 行政區域漢族亞群的遺傳特徵 there are 2 internal divisions of Northern Han and 4 internal divisions of Southern Han furthermore there are outliers such as Han Chinese from Jiangsu,Tianjin,Shandong and Macao.
The explanation the paper gives is the natural boundary of the Chang Jiang,and constant floods and warfare lead to population movement.
If you're going to argue that today's Fujianese are pure Minyue then explain their Y chromosome affinities towards Northern Han Chinese.
You have never provided anything of value other than cherrypicked texts and your own speculation.
