In Ben Fountain's Novel Billy Lynn's Long Halftime Walk (2012), Billy Lynn, who participated in the halftime show of the Super Bowl with his comrades, had been in a dilemma: whether to be a deserter or to return to Iraq to share life and death with his comrades. Faison was a beautiful and kind cheerleader. She had a major impact on Billy's choice. She fell in love with Billy at the first sight. In the story mainly about soldiers, what is the author's intention of creating such a female character? Therefore, Faison is a very important role in this novel. As the novel progresses, the symbolic meaning of "Faison" is constantly strengthened. For Billy Lynn, Faison is no longer just a beautiful and sexy woman in real life, but a symbol in Billy's imagination. In the exploration of the symbolic meanings of Faison, the paper mainly discusses three of them. First, Faison symbolizes the good and ordinary life Billy has been pursuing. Second, Faison stands for the public misunderstanding of and contempt attitude to these poor soldiers. Third, Faison represents Billy's faith in life. She becomes a "mirror" of Billy, which hardened his resolve to make his own way.
