I have been researching on my hakka lineage off and on and it's very interesting. There's even evidence that hakka was the national language at certain juncture in tiong history.hakka genealogy is very interesting. As of now, even the experts have no solid idea of what the full Hakka picture is like. But I have my own conjecture and that is they were the original Han Chinese. The "guest" label was applied to them only because they sought refuge in the Southern provinces away from the invading Northern barbarians who subsequently took over China.
and she is pretty!
And for interest sake, many rich hakkas here own Chinese medicine shops. I haven't met one running the shop that can't speak the dialect.
