This article aims to introduce some knowledge points of Northern Qi society to everyone in concise and easy-to-understand language. It will not focus on Gao Su throughout the article. It mainly extracts keywords in chronological order based on the experiences of Gao Su recorded in Northern Qi books and inscriptions. Each section is centered around a keyword.
Fixed reference bibliographies such as "Book of Wei", "Book of Northern Qi", "Book of Sui", old and new "Book of Tang", "Tongdian", etc. Will no longer be marked repeatedly. Since the modern works on the study of Northern Dynasties society are quite abundant, the individual reference materials for each section can be kept at no more than three. These references and extended reading materials that do not use their viewpoints but are worth reading are marked at the end of each section.
