2. "I" wrote my name and the name of my village in big black letters on the paper boat. What's the purpose?

Lonely "I" hope to get friendship or hope that my blessing can be passed on to people far away.

3. What did the poet describe around the "paper boat"?

Around the "paper boat", the poet described the children's whimsy. First, I thought that the paper boat with the name of "I" and the name of the village where "I" lived could be obtained by people in different places. Then I thought that Xiulihua could be safely brought to the shore by boat. Then I thought that the ship in the sky could be put down to compete with my ship. Finally, I thought the sleeping fairy in my dream was sitting on a boat.

4. What is the dream in the last sentence? Please talk about your understanding in combination with poetry.

Maybe it's yearning for the outside world, maybe it's yearning for friendship and recognition, maybe it's bringing blessings to people far away, maybe it's hoping that the boat of one's life will spend safely in stormy waves.
