The most fundamental skill is theoretical literacy —— Message to young cadres ② The light of theory passes through ancient and modern times, and the power of theory overcomes the enemy. President Xi pointed out: "young cadres need to master many skills to be competent in leadership. The most fundamental skill is theoretical literacy." If a nation wants to stand at the peak of science, it cannot be without theoretical thinking for a moment. Theory is the guide of practice, and theoretical literacy is the core of cadres' comprehensive quality. If Party members and cadres have theoretical literacy and Marxist stand, viewpoint and method, they will have a powerful ideological weapon to understand and transform the world, so they can well guide practice and promote work. If there is no theoretical literacy, it will not only lead to a weak position and unclear direction, but also lead to unclear ideas and unscientific methods. It seems busy, but it is actually useless. During the Yan'an period, the reason why our party insisted on "eating small rice and attacking the mountain of theory" is that "only when Communists have revolutionary theory can they get a clue from the complicated things and find a direction from the changing movement can they do a good job in the revolutionary work". On the new journey, the task we face is more arduous and the situation is more complex. If the theoretical arms are not in place and thorough, it will be difficult to overcome various risks and challenges. Only with strong theoretical literacy and theoretical firmness can we ensure firmness in politics, party spirit and behavior. The improvement of theoretical literacy is inseparable from rich learning practice. On the one hand, young cadres should strengthen theoretical study, enrich their theoretical foundation, consciously use the party's innovative theory in the new era to observe the new situation, study the new situation and solve new problems, so as to promote all work in the right direction and in accordance with objective laws; On the other hand, we should adhere to the combination of theory and practice, pay attention to learning true knowledge and understanding the true meaning in practice, strengthen training and increase ability.
