This book is in Chinese. What you see here is the "collector's limited edition". Detention Center by Dian Qiu Gu Jiu won the 2018 Juneflower International poetry Prize. It is a long poem written by the poet on and off when he was working as a prison guard in the Detention Center in Guangzhou, China. It took him several years to finish, and because of the poem, all of his poems were banned by official publications. Critics in China compare this poem to Howl by Allen Ginsberg, and they found the "howl" in Dentention Center is louder and more like hell.
