What safety matters need to be paid attention to when traveling in the United States?

First, carry medicines with you. If you feel unwell or have an accident while traveling and you don’t understand the language, you can help yourself immediately and then seek help or call 911.

Second, keep your valuables such as mobile phones, watches, passports and other items. Once lost, it will not only cause trouble to find and replace them, but also affect your mood during travel.

Third, do not travel at night. The safety level in the United States is not as high as imagined. It is easy to encounter dangers when traveling at night, so try not to travel at night.

Fourth, do not buy dangerous items, such as knives, as gifts. If you are caught during a patrol inspection, it will be difficult to deal with the matter afterwards, so just don't bring them.
