I'd like to ask, why are the covers of the poems of Blue Star Poetry Library (People's Literature Publishing House) all covered with this blue-painted pattern?

In my personal opinion, this design should be aimed at expressing the flexibility and freedom of poetry creation, not sticking to fixed rules and regulations, but acting casually.
