The “overseas characteristic” of Chinese literature is a very general concept, and its creation is closely related to the writer's writing style and personal life perception.If there is an “overseas characteristics”, I think it should be that immigrants are affected by double culture or even multiple cultures at the same time, which must have culture shock and may also cause identity anxiety. But after this stage, people with sensitive personal life perception will have a process of reflection on themselves and their mother culture. Then it will gradually shift from focusing on external world phenomena to focusing on the growth of the individual's inner self. Chinese-american writer Chen Qian can be said to be an excellent representative of this aspect. “Leaving” is a basic tone in Chen Qian’s works, and the protagonists in Chen Qian's works often leave for better adherence, adherence to self, adherence to their own inner dedication and dream. This paper mainly discusses why the protagonists in Chen Qian's works leave and why they stick to them, in order to explore the influence of individual self-consciousness and mirror image on their own growth, and further explore how Chen Qian views the meaning of life existence.
