1, do not hitchhike, travel in the United States, and must not hitch a ride. This is due to the social security situation in the United States.

Free riders are often robbed of money or humiliated and so on.

Some gangsters saw the women walking on the roadside and took the initiative to stop.

If he is mistaken for kindness, it is nothing less than giving sheep a tiger's mouth.

In such a situation, it is best to say no to cold words and not to chat more frequently.

Because some gangsters, including young girls, are waiting for hitchhiking, getting on the train and threatening to get money by means of threats.

2, do not take the subway at night, the subway in New York is extremely messy. At night, it becomes a gathering place for members of the underworld.

Drug addicts, thieves, hooligans and drug traffickers gathered here, making the whole atmosphere shudder.

5, modesty is not virtue, but the Chinese regard modesty as virtue.

But Americans regard it as a synonym for hypocrisy.

If a fluent English speaker humbly speaks English badly and then speaks fluent English, Americans will think that he has lied. He is a duplicity and an affectation.

Therefore, when interacting with Americans, they should be bold enough to express their abilities. One is ten, the other is ten.
