Novel metaphor

This should be summarized by your teacher! Don't laugh at me: the novel is the breadth and vastness of the sea, but it always has a shore. Poetry is the depth and magnificence of the sea, but it is hard to see the inside story. Prose is like endless waves on the sea, blooming, scattering and gathering! Your teacher's summary of Baidu is probably nothing. Please ask the students who choose this course next year!
