本书为作者二马三十年来的自选作品集，多数曾发表在各类媒体。作品京味十足，幽默乐和，读来既解压，又解渴，大部分是亲身体验，很多作品的得来还是像蒲松龄一样，是与旁人聊天聊来的。舒乙对其作品有这样的评价："冯亚东的文章都超短，可以算是小小说，这是一种新品种，干巴利落脆，抖一个包袱就结束，短小精悍，轻松之至，可读性颇强。" (The book is the work collection of the author named Erma in thirty years. Many of the articles were published by various media. These articles have obvious Beijing style, humorous and full of joy. Reading them can relieve stress and quench the thirst. The majority of the works are author's personal experience. Many works were inspired by the communication with others like Pu Songling's works. Shu Yi made such a comment to his works: "Feng Yadong's articles are very short, which can be called mininovels. This is a new style, short and sweet. And it is easy to read.")
