When the sun is shining, daffodils are in full bloom. What does the rose wall mean when it is embarrassing? What's the moral? Thank you all

The two willows at the door are already spreading their leaves and dancing green; On the wall of the hospital, countless green plants have stretched out their green tentacles ... and covered a wall! Ross! There is a faint scent of flowers in it! This strange sight, which exists purely in imagination, is a means of fate.
