Divergent thinking, you can discuss the "status of patches" (patches used to make clothes look good, but now clothes look good with patches)
You can also discuss the relationship between quantity and quality (when there are many patches, everyone pays attention to his beauty and ugliness, but now there are fewer)
You can also discuss "the relationship between the protagonist and the supporting role is changing"
You can also discuss "appearance and inner" (the reduction of patches directly leads people to pay more attention to his appearance, ignoring his original function of simply mending clothes holes)
In short, don't be trapped by this sentence of the topic, and think about it in connection with reality.
I hope it will inspire you.
