An APA citation is a brief in-text citation （not a footnote） that provides information on a text's author and date of publication. This brief citation is keyed to a full reference in an alphabetical list of works included at the end of the paper. A complete bibliographic citation thus has two parts: （1） the in-text citation in the body of the paper, and （2） the bibliographic reference in the list of works cited.
（1） In-text citation
Zhao （2000） argues that Chinese nationalism has traditionally been inward-directed rather than outward-directed and expansionist.
（2） Reference in the list of references
Zhao, S. （2000）. Chinese nationalism and its international orientations. Political Science Quarterly 115, 1-33.
Let's consider first the in-text citation and then the list of references and individual references.
