beautiful girl.in Chinese Tang dynasty,people think that fat girls or women are very beautiful.such as 杨贵妃

To call someone fat is very offensive in England but to use a more polite way you could use Cuddly, plump or chunky. People also use over weight, big boned, heavy or large to describe someone with a weight problem.

You haven't stated in what language in particular? In English it is generally considered insensitive and indecent to call someone names. But, as you don't seem to mind it, I guess a not so offensive term can be 'obese'. Colloquially, I guess, the most popular term for someone obese is 'fatty'. I hope you lose weight though. I don't mean it for not anything related to beauty, but for health reasons. Cheers :-)

Other words for 'fat' whether decent or not : corpulent, fleshy, heavy, plump,rotund, gross or broad in the beam ( informal one).
