How does Joy actually get into China once she arrives in the book, Dreams of Joy?

When Joy arrives at Chinese passport control, she repeats some of the propaganda mottoes she learned at the Chinese Student Democratic Association, assuring the agent that she's here to help build the People's Republic. The agent allows her to enter the country, but not before he confiscates her American passport. Then he takes Joy to have her bags searched. They remove many "bourgeois" items from Joy's luggage, including her brassieres. The luggage inspector pockets half of Joy's cash and then poses for a picture with her to be hung on the Comrade Wall of returned Chinese.
