There are taiwanese minnan radio prog www.cbs.org.tw .sadly it is too poor.The host need to learn more about minnan (any sect)but shouldn't mix with mandarin.
Example- there are at least 10 words for (mess) in minnan.why she uses a mandarin version in minnan sound.
I feel very sad that taiwanese wu origin ,northern province like shandong.xi,etc people have no chance to learn their languages.Their children are not supposed to learn minnan and hakka in school.
