Ming Confucian Case Studies is one of China’s leading academic history monographs and is also a work on the formulation of a case study. In recent years with in-depth study from literature investigation into Ming Confucian Case Studies, issues related to research on the principles and methodology have been put on the agenda. This paper argues that contentment, purpose, work and ontology are important compilation principles and methodology that pervade Ming Confucian Case Studies; and they also were important references Huang Zongxi utilized when editing Ming Confucian Case Studies in selecting and setting up the case studies. Highly esteemed contentment is a kind of learning spirit that emphasizes subjective consciousness; and purpose is an affirmation and elevation of contentment that is the brain of scholarship. Valuing work and devaluing ontology is an important rule that Huang Zongxi took as a norm for Yang-Ming idealism and is an important reference to judge whether later works of the Yang-Ming school were a continuation of the idealism. Contentment and purpose, and work and ontology were not only the standard for selecting and setting up cases in Ming Confucian Case Studies, but also one of the paths that later scholars who study Huang Zongxi and Ming Confucian Case Studies cannot be without. And also they are a very good reference standard for those who later edit academic histories to use.
