There is an existential spirit of "no fantasy and despair" in Zhi Zhi's early poems (though he may not know this term at that time). What deserves special mention is his Mad Dog, which can be said to be a unique work in China's poetry. The philosophical depth of reflection on ontology is enough to compare with some works of Dostoevsky. Admittedly, he also wrote some mediocre works, but as long as we think about it, it was an era when jokes could lead to jail, and we should understand and even respect it.
