Scientific evidence on who speaks Hakka

[Kelvin <kachie-hakit@account-pro.com>]

Dear everyone,
Chunfat says we must have scientific evidence to prove how many people
are proud of their Hakka culture, and find out how many people identify
their mixed ethnic roots as opposed to one ethnic identity.

Is scientific evidence necessary? Will it be objective, will all the
people reply to such scientific experiments?

I'm not sure if scientific evidence will be sufficient. After the
conference in December, I'll remember to share everything I see and
hear, so all of you will know what's happening in Toronto. I think it's
also important to learn about others in different parts of the world.
