There are several kinds of Hakka dialect, but I can't understand any of them.
There is only one kind of Hakka dialect. Generally, the Hakka dialect in Meixian county is regarded as the most authentic, and all the other places have a local accent.
In addition, there are some Hakka versions of grabbing red envelopes and some daily WeChat expressions, which can be used for New Year greetings and begging for red envelopes.
