How to understand the criticality of philosophy

Marx's understanding of philosophy has gone through a dialectical and critical development process from "honoring philosophy", "eliminating philosophy" to "changing philosophy". In this process, Marx's philosophy has realized the greatest philosophical change in the history of philosophy, specifically in the interpretation and grasp of the worldview, philosophical way of thinking, and the understanding of human beings. Criticism in philosophy is different from criticism, it is abandonment, it is reflection. Criticism is a one-sided accusation of faults, whereas criticism is to point out faults and recognize their correctness, and then to correct the faults and inherit the correctness, so as to achieve the purpose of abandonment and put forward one's own theory. Therefore, we say that the purpose of critique is to rebuild, to promote, and not to attack personally. Reflection is the way of critique, through which we can both discover errors and build new theories. Criticism means that a theory not only y exposes the imperceptible problems of previous theories or things, but at the same time inherits and promotes the previous things, and reaches a new level and builds up a new theoretical framework.
