What do you need to prepare and pay attention to when going to the United States to watch the NBA All-Star Game?

The bag must be searched when entering. Long-barrel cameras and video cameras may be searched and stored in a certain office of the team. They will be picked up after the game. In fact, you can just take pictures with your mobile phone. You can’t bring food in, hahahaha. Here, I shamelessly think of a story that happened to one of my classmates, hahahaha. It's full of American fast food, hot dogs, nachos, cola, etc., and it's not cheap, so it's better to eat around before going in.
