The hui chinese is not stupid to keep the moslem rule and they left moslem long ago. Must disown their own kid if their kid leave islam instead the hui chinese has become han chinese and retain their hui id. No racial profiling unlike the south east asia here.
Some hui practice not to eat pork and that is all. Non halal food they still will eat as long no pork but other islam belief they already abandon. Their heir certainly will eat pork after assimilate and keep marry with the han and keep producing yellow skin kids.
