The large Boeing 747 aircraft slowly landed at New York International Airport. More than ten minutes later, my husband and I were dragging heavy luggage and rushing out of the crowded crowd. In the vast airport hall, all kinds of people swayed in sight. White, black and yellow people, rich bosses dressed in bright and straight clothes, fashionable girls dressed in avant-garde style, shabby and ragged lower-class people, can all be seen in this hall. All kinds of people gather here, as if they have embraced the whole world.
