(Ordinary and relaxed with novelty and rigor, Zheng's style extols the true, the good and the beautiful, meanwhile offers in-depth and extensive knowledge. With high tension, his essays are of high vitality. Zheng's works were created under a wide range of subjects, covering what was heard and seen in daily life as well as feelings about historical events. This book is made up of Zheng's representative works carefully chosen, divided into 4 parts ("Mountain Miscellanies", "Petrel", "Seclusion Miscellanies", "Old Friends and Things"). The first 3 parts consist of essays from the essay collections with the same names. The part "Old Friends and Things" consists of his works in memory of friends, all of which are representative and readable for contemporary primary and middle school students. Supposed to be a good extracurricular companion for teenagers, this book contains artistic illustrations to enrich their inner world.)
