In Zhang Ailing's works, not only the moonlight has always had the function of bearing profound connotations, but also the names of some things and characters. In a lot of hate, the hero's love also makes me feel a heartfelt pain. The governess fell in love with the male host, but the male host already has a family and an eight-year-old daughter. It stands to reason that the man's family should be a family full of warm atmosphere, but the man's marriage is a traditional matchmaker and has no emotional foundation. The cultural gap and values between them lead to this lovelessness. However, the governess also loves her female students and can't bear to destroy their happiness, take away their father and hurt her sick mother. Therefore, for a tutor, her feelings are doomed to be a tragedy. There is an image of "Moon Cave Gate" in the article. "She is also reflected in the mirror, and she can't shut him up in this month's hole for the time being. That mirror will soon be as desolate as the moon. " This is both an extension and a contrast. The full moon gate has a heavy history, which is the disappointment that love can't complete, and it is the hidden pain of history, which no one can solve. At the same time, it also implies that the reader's love did not get a happy ending like this full moon door. On the contrary, this month, Dongmen is like an old moon, like a mirror, and the tasks and life it captures are inevitably bleak as a dream. The work separated a pair of lovers with the "Moon Gate", which played a foil role for Lao Yan's departure and increased the sensibility of the story.
