Download from here: 大灰狼罗克 pdf.
Some students asked me about recommended readings. Zheng Yuanjie is one of my favorite writers. 大灰狼罗克 embodies 50 short stories, some of which bear a sense of Chinese-style black humor. I only found simplified version without pinyin, but you might be able to get one with pinyin at amazon or halfbook.com.
