In Foucault's idea, the art of governing consists of introducing economic considerations into political practice; Governing a country means managing the economy of the entire country, with the aim of promoting the economic development of the country and the well-being of the population. The application of governmentality also exists in the current education system; a series of management strategies are applied to control the education of students, this is not only from government authority, but based on globalized competition in education. In this essay, I will discuss how Michel Foucault's governmentality is implicated in Hong Kong teacher education. To govern as a verb, it must imply both the object governing and the object governed. While to govern something, it means that the object is in a state that is awaiting improvement. In another way, this state of “to be improved” is the prerequisite for being governed. Improvement is the objective that the governing authorities set for the governing body, this could be the increase in gross domestic product, full employment of citizens, etc. Without these objectives, the governing authorities cannot carry out the action of governing, and the governed body cannot be governed. In other words, governing authorities without a reason for existence, governmentality cannot function. Foucault's inquiry into governmentality, centered on the problem of personal subjectivity, is about being concerned with the problems of “who we are” and the problems we face. Foucault also emphasized that the main objective was not "what are we" but to refuse to be "what are we".
