What does the poem "Bed in Summer" mean?

Robert Louis Stevenson's Sleeping Bed in Summer. Zhang Heqing Author: robert louis stevenson Translation: Zhang Heqing In winter, I get up at night and get dressed by yellow candlelight. I dressed in dim candlelight. In summer, on the contrary, summer is very different. I have to sleep during the day. I must sleep during the day. I have to go to bed. I have to go to bed. Birds are still jumping in the tree, seeing birds still jumping in the tree, or hearing the footsteps of adults, and passing me in the street. When you can fall asleep, when all the sky is clear and blue, the sky is so blue and bright, I want to play so much that I have to go to bed during the day. Is it difficult for you? How to sleep in broad daylight?
