If what you want to do is catering, please make it clear. In places where more than 90% are Muslims, it is best not to consider halal. You have to push 98% of the guests out, because as long as there are ethnic groups eating together, even a Han nationality will choose to enter the Muslim restaurant, so please pay attention to your choice.
If you want to make clothes, you should be able to make them. It depends on how you run.
