Chairman Mao once said: Strengthen discipline and the revolution will be invincible. Discipline is the guarantee of carrying out the line. During the revolutionary war years, our party and the army led by our party won one battle after another by relying on iron discipline, and finally established People's Republic of China (PRC). In the era of revolutionary construction, our party relied on iron discipline to lead the people of the whole country to overcome one difficulty after another and build a poor country into a thriving socialist power. Facts have proved that party discipline is the lifeline of our party. Especially at the moment of expanding reform and opening up and realizing the great cause of national rejuvenation, all kinds of temptations are frequent. Without iron discipline and strong concept of discipline, party member's cadres' thoughts are easily corrupted, and the great Chinese dream can only be a pipe dream. Therefore, "strengthening discipline education" is of great significance.
