American gun culture is related to American history. The victory of the United States from the founding of the people's Republic to the war of independence was related to the armed forces of the whole people. Therefore, after the founding of the People's Republic of China, the Second Amendment of the Constitution clarified the right of citizens to legally own guns. Some time ago, it was reported in the news that cowboys boycotted the government's land acquisition, which is a good embodiment of this right.
After buying a gun, you can put it at home, or you can take it to a shooting range or hunting ground for shooting and hunting. You don't need a special permit. And carry it with you, the term is CCW, which means carry it with you in concept. This has different regulations in different states. Some states don't allow it, some apply for it, and some states have to be trained to get a carry-on permit.
