Hui people are Muslims. When it comes to Muslim restaurants, the first thing that comes to mind is not eating pork. In fact, Muslims clearly stipulate not to eat those dirty animals. Pigs eat, drink and sleep all day. Muslims think they are lazy, and pigs eat their own shit, which is really dirty, so Muslims don't eat pork because of the attributes of pigs. They think eating dirty things like pigs will become impure, so they don't eat them
In addition, they have a rule that they will not eat poultry slaughtered by non-Muslims, which they think is also a bad behavior. Moreover, they will only eat livestock slaughtered by Muslims, and will not eat livestock that died of natural causes. Hui people usually eat more pasta. In their recipes, pasta is the staple food, and rice only accounts for a relatively small part. And when it comes to pasta, I believe everyone knows that the famous Lanzhou Lamian Noodles is a typical Islamic pasta.
Generally speaking, there are no restrictions on what we eat, but there are still many restrictions on what Hui people eat. They usually eat chicken, beef and mutton, and then eat rice and noodles. Vegetables are not much different from ours. It seems that they can eat most vegetables, but it seems that Muslims prefer to eat meat. Those vegetables are rarely seen in Huimin restaurant, and most of them are mainly meat.
