The Vietnamese word "tu thân" can be understood as a verb that means "to self-improve" or "to cultivate oneself." It refers to the process of personal development, self-reflection, and moral or spiritual growth. This concept is often associated with improving one’s character, behavior, and knowledge.
While "tu thân" primarily means self-improvement, it can also imply self-discipline in a broader sense, such as adhering to a set of ethical or moral standards. It’s important to note that it conveys a sense of responsibility towards oneself and one’s actions.
