This is an open question that can be answered from any angle. For example, "shallow vulgarity" is reflected in the language, and the language of the whole poem is popular and clear; "Strange" is reflected in the description of scenery, and the selection of materials is distinctive and meaningful. In particular, the description of "the fisherman's clothes have been lost" is poetic and picturesque, which also shows the poet's reverence for the fisherman.
