This trip to the United States is like a colt crossing the river. No matter how much we heard from others about their experience and the matters needing attention before going abroad, it is best for us to experience the life here in person after all. For example, everything went well from Wuhan to Denver and according to the procedures, when we checked our luggage in, went through immigration and customs, and took public transport, which made me feel that what I heard from others was an alarmist talk. Some said that we should be on the alert against the enthusiastic Americans, especially the black, which made me worry a lot before going abroad. It turned out that the Americans that I met all the way were very polite and did not pay attention to me or strike up a conversation with me because I am a foreigner. But they would come to help you if I was in trouble. For example, when I could not find the boarding gate and or carry my luggage, many Americans came to help me and then left. The day before yesterday, a friend needed change to take the bus. A black man took out all his money but could not exchange the fifty Yuan for us, and then gave us his 20 dollars directly to take the bus.
