In Taiwan Hakka is the 3rd most popular language, and the MRT in Taipei makes all announcements in 4 languages; Mandarin, Minnan, Hakka, and English.

It is also a minority language in Hong Kong and neighbouring Guangdong.

A Hong Kong Hakka friend of mine said they did not understand the MRT announcements.

Is the Hakka spoken in Taiwan the same as that in Hong Kong and Guangdong?
