3. The meaning of the poem is: Perhaps the owner of the garden cherishes moss, afraid that my wooden shoes will leave footprints on it, and he tapped Chai Men, but no one came to open it for a long time. The flowers in the garden have just opened, and the spring scenery represented by these flowers can't be caged. A blooming apricot flower sticks out from the wall.
