    百分百真刘秀,6722纯碰瓷

    这支O-Y20928缺乏江苏和安徽等地的刘秀系王国像楚国、沛国、彭城国等国的支系,不是真正的刘秀。
    真正的刘秀应该是O-MF6722,刘秀是湖北人假冒的,在河北称帝之后,后代主要封在河北山东江苏安徽等地区,O-MF6722全方位覆盖刘秀家族的东汉封国,在所在刘秀封国区域都有独立分支。
    O-Y20928应该是刘买家族,刘买后代在刘秀称帝建立东汉之后受到优待,全族百人封王封侯,封地主要在山东河南等地。也就是东汉皇帝已经换了,但刘邦后代依旧是权贵持续大爆发。
    • Anonymous 真正的刘秀应该是O-MF6722,刘秀是湖北人假冒的,在河北称帝之后,后代主要封在河北山东江苏安徽等... 别招笑了,东汉楚国一代就没了,刘英五个儿子全降级为侯和列侯,后面能爆发就有鬼了,至于沛国,20928谁告诉你没有江苏支的?而且安徽能多就有鬼了,孙坚孙策南下都把江东士族图了一遍,你看三国时期安徽有几个刘氏藩王冒头的?刘秀10个儿子4个都分封在山东,子孙也是山东最繁盛,20928下游总共43支,光山东支就20个,6722五十几支,结果山东支还比别人少俩,这算哪门子刘秀?
    • Anonymous 真正的刘秀应该是O-MF6722,刘秀是湖北人假冒的,在河北称帝之后,后代主要封在河北山东江苏安徽等... 6722还有个东汉开国时期的甄氏家族,哪个时间线里面甄皇后的祖上是刘秀的?

    这才是真刘秀!
