The Fengsu tongyi 風俗通義 "Comprehensive meaning of customs and habits" is an enyclopedic collection of various matters compiled by the Later Han period 後漢 (25-220) scholar Ying Shao 應劭, courtesy name Ying Zhongyuan 應仲瑗. Ying Shao came from Runan 汝南 (modern Xiangcheng 項城, Henan) and was made a court gentleman (lang 郎) in 173 and rose then to the post of magistrate (ling 令) of Xiao 蕭, then of Yingling 營陵, and was finally promoted to governor (taishou 太守) of the commandery of Taishan 泰山. He ruthlessly suppressed the uprising of the Yellow Turbans 黃巾, when it inundated his commandery. In the aftermath he prepared to receive the warlord Cao Song 曹嵩 (the father of the famous Cao Cao 曹操) and his son Cao De 曹德, but before they arrived in Taishan, they were killed by general Tao Qian 陶謙. Fearing revenge by Cao Cao, Ying Shao fled to the territory of the powerful general Yuan Shao 袁紹 who made him commandant for military counsel (junmou xiaowei 軍謀校尉). Ying Shao also compiled a lot of books, like the Zhonghan jilu 中漢輯錄, Hanguanyi 漢官儀 or Liyi gushi 禮儀故事, as well as some short comments to the Hanshu 漢書. He seems to have specialized in the administrative history of the Han dynasty.
The 10 juan "scrolls" long Fengsu tongyi was written in the aftermath of the Yellow Turban uprising in the hope that the encyclopedia might be useful for the reconstruction of the shattered fundaments of the empire. Ying Shao tried to describe a lot of common matters valid as knowledge among the population, with the incentive to establish a standard of what was important for common knowledge and state administration. His chapters Yanli 愆禮 and Guoyu 過譽 are critical towards the lavishness of his times and the superfluous aspects of many rituals and open praises made at the court. The chapter Shengyin 聲音 is very important for the history of music. The chapter Shanze 山澤 is a valuable supplement for the history of ancient China's rivers. Parts of the chapter Guishen 怪神 served as source for the collection Soushenji 搜神記. The Fengsu tongyi was praised as a rich source on many aspects of Han period life. Later it was almost forgotten and is barely investigated.
The received versions have all 10 juan. Only the version in Wu Wan's 吳琯 Gujin yishi 古今逸史 has 4 juan. Yet the imperial bibliography Jingji zhi 經濟志 in the official dynastic history Suishu 隋書 speaks of 31 juan, including one additional juan of "records" (lu 錄). The bibliographies in the histories Jiutangshu 舊唐書 and Xintangshu 新唐書 record 30 juan.
The size of 10 juan is documented in Song period 宋 (960-1279) sources. Su Song 蘇頌 during that time wrote a critical preface, the Jiao Fengsu tongyi tixu 校風俗通義題序. A lot of chapters were apparently lost before the Song period. Of the 20 lost chapters, at least the names are known from records by Su Song 蘇頌 and Lu Xinyuan 陸心源, but their order is unknown. Kang Zongrong's 康仲容 Zichao 子抄 from the Liang period 梁 (502-557) and Ma Zong's 馬縂 Yilin 意林 from the Tang period 唐 (618-907) both quote from the Fengsu tongyi, as well as the large Song period encyclopedia Taiping yulan 太平御覽.
The oldest print dates from the Dade reign 大德 (1297-1307) of the Yuan period 元 (1279-1368)
which is based on an earlier edition by Ding Fu 丁黼 who had used two different versions of the Fengsu tongyi for his lost edition. The Yuan print was reproduced during the Ming period 明 (1368-1644) by Yao Ruo 姚若. The Fengsu tongyi is included in the collectanea Han-Wei congshu 漢魏叢書, Gezhi congshu 格致叢書, Gujin yishi 古今逸史, Bai mingjia shu 百名家書, Zishu baizhong 子書百種, Mishu ershiyi zhong 秘書二十一種, Siku quanshu 四庫全書 and Sibu congkan 四部叢刊. There is a chapter on families (Xingshi pian 姓氏篇) in the Zhangshi congshu 張氏叢書. In 1980, the Tianjin renmin press 天津人民出版社 published Wu Shuping's 吳樹平 commentary Fengsu tongyi jiaoshi 風俗通義校釋.
