proportion testing

Hi everyone.
May i please ask for some help?
Let say i have gender(F/M) and ethnicity(Chinese/Indian/English).... and i wanna know how would i do in order to test if the proportion of male chinese is different from male indian, or proportion of male indian is different from male english and that of male chinese with male english and do the same for female. Is there any command in STATA allowing to do this?

Your help is greatly appreciated. Have a good day.
