《问故乡》是一本以讲述为主要方式的纪实作品，分为"天干集"和"地支集"两部分。前者来自官场，后者来自平民；前者多为耳闻，后者多为目睹；前者高屋建瓴口述历史，后者操劳生计忙碌繁琐；前者讲述的是宏观努力，后者多是草根故事人物命运。同时阅读二者才能看出一个地区的发展脉络，也才能解答关于草根生活的良心追问。 (This Is My Hometown is a documentary work from a narrative perspective, and it is divided into two parts, "Heavenly Stems" and ""Earthly Branches". The former part talks about officers, while the latter tells the stories of civilians; stories in the former mostly are heard from others, while those in the latter mostly are witnessed; the former records the history in a general way, while the latter describes the busy and hard life; the former represents the great efforts on the macro view, while the latter shows the fates of the grassroots. Only the two perspectives are perceived, can the development traces of a place be clearly uncovered, and questions about the life of the grassroots be better answered.)
