What does the slogan posted at the Hui Min Restaurant mean that no outside dishes are allowed?

1. Explain that his Hui cuisine is authentic. Dishes from other ethnic groups, such as pork, must not be allowed into the store.

2. Be responsible for other customers. If you see or smell something bad, those who eat at Kemin Restaurant are basically Muslims. The authentic Muslims will vomit even if they smell the smell of pork, not to mention eating it. .

So the Hui Min Restaurant says no outside dishes are allowed.
