2. This poem expresses that I am willing to be a boatman, to serve the villagers who explore and transform nature, and to repay the thoughts and feelings of raising my mother and motherland.
3. No, "the other shore" is the poet's goal. To reach the other side of the ideal, the poet is determined to start from an ordinary boatman, willing to send those who pursue the other side of the ideal to their destination first, and at the same time realize their unremitting pursuit of the ideal. If it is changed to "I want to be the boatman of this ferry", it will be too straightforward and lack deep meaning and connotation.
