Pay attention to proper language when talking to black people, for example, don't use contemptuous words like nigger.

Generally speaking, black people are easy to talk to and you can make friends with them.

Although there are more blacks in Detroit (25%-35%), whites are still in the majority, while Asians are few (2%-3%), so you should learn to take care of yourself.

Don't wander in the street at night, especially in the early morning. It's dangerous. Not only is it a bad person, but it is also dangerous for you to meet the police, because they may suspect that you have drugs or weapons and shoot you.

Detroit used to be a motor city, so the air pollution there is more serious.

Because there are few Asians, food is definitely uncomfortable, so pay attention to food safety.

Then there is the weather. It is extremely hot here and extremely cold in winter.

I heard all the above. .
