This article was originally written nearly ten years ago. At that time, I was a novice undergraduate who had just started to get involved in Southern Dynasty literature. I wrote it with the fearless attitude of an ignorant person, and wrote a beginning that was full of historical errors and could not bear to be read. Ten years later, as a teacher with a thesis titled "The Acceptance and Feedback of the Culture of the Southern Dynasties in the Northern Dynasties," I feel that I have enough knowledge to rewrite this article. From another perspective, I chose such a doctoral thesis topic, which seems to be my destiny that began to emerge ten years ago with "Song of the Four O'clock in the Midnight". I haven't written in a long time, and my writing style is worse than before, which is ridiculous.
