We must walk our talk.
Example, I myself speak dialect anywhere, everywhere,
and a lot of times I can be the dialect initiator so that
whenever people see me, they start to speak to me only in
dialect.
Or perhaps create the environment conducive to dialect.
Furthermore, I do not subscribe to the preconception that people
like school teachers, principals, doctors, lawyers, or maybe media
people, you must speak English or Mandarin to them. I
don't care who are they, when I meet these people, I
converse to them in dialect and whether they choose to
reply in dialect or not is their matter.
many times speak dialects as native tongue give a good
connection but this is slipping away.
