Hokien are not originally vulgar or ugly looking.
If you know our Singapore history majority of the Chinese who
migrate here are coolies or labours, farmers, fishermen or samsui
women etc Most of them are poor education background and poor diet
habits. Due to hardship and frustration it is naturally language
becomes vulgar and ungrammatical. Some how the generation that
follow tends to inherit all the vulgar speech from the previous
generation
To break away from this social sigmas, Now these generation has
been much more educated, are well fed, better looks should put away
those vulgar and unseemly words. Speak proper good hokien
sentences. Don't know go and learn from those mainland china or
Taiwan. Visit the home town in Hokien province. or watch Hokien
movies
I know recently in my area, there are ladies who migrate from China
to Singapore recently are good looking, tall, sexy, well spoken,
eloquent hokien and mandarin. If she did not tell me she is from
Hokien province I don't even know.
If you observe at how the Taiwanese speak Hokien you can see how
much difference.
