No.
Original text: The alley was long and winding, without doors or windows. I knocked on the thick wall with an old key. The alley is curved and long, has no doors or windows, and has thick walls. It is full of symbolic meaning. It is a closed and isolated alley, and the boy's nature is full of desire for the outside world and yearning for freedom. Therefore, The poet "taking an old key and knocking on the thick wall" is an unconscious behavior of the poet trying to get out of the alley and embrace freedom.
The scenes depicted in "Alley" will be familiar to teenagers of that era, and they may even have personal experience. Whether it is a "curved and long" "alley" or "I took an old key and knocked on the thick wall", they can all be regarded as real descriptions of real things. However, the charm of Gu Cheng's poems lies in the meaning behind the words. The seemingly plain and ordinary descriptions are actually full of meaning.
