The garden day is interesting, although the door is always closed, how to understand it?

Walking in the garden every day is also very interesting. Although there are doors in the garden, they are often closed. This sentence means that the author chooses to live in seclusion, get along with himself, often only moves at home, rarely associates with others and has no visitors, so the door is often closed. Poems with similar meanings include: My road is covered with petals-I swept it for others, and my thatched cottage door has been closed-but now it is open for you.
