The article points out that "today, more than at any time in history, we are closer to, more confident and capable of achieving the goal of the great rejuvenation of the Chinese nation. Half of those who travel a hundred miles are 90%. The great rejuvenation of the Chinese nation can never be achieved easily by beating the gong and drum. The whole party must be prepared to make more arduous and arduous efforts." This important political statement connects history, reality and future. It not only shows our Party's confidence and strong determination to achieve the great rejuvenation of the Chinese nation, but also serves as a solemn reminder to all Party comrades that the great cause of national rejuvenation must go through tenacious struggle and unremitting struggle. Today, the national rejuvenation has entered an irreversible historical process, and we are ushering in an extremely bright future. At the same time, we are also at a juncture when it is more and more difficult to advance, more and more dangerous to advance, but if we do not advance, we will go back. It is more urgent for a boat to wander in the middle of the mountain, and it is steeper for a person to travel halfway up the mountain. At this critical juncture, we need to be modest and prudent, guard against arrogance and impetuosity, and continue to struggle. We should constantly cultivate opportunities in crisis, open up new situations in changing situations, and work hard to achieve the set goals with unswerving perseverance, and tirelessly promote the great rejuvenation of the Chinese nation with the sobriety of half of those who travel a hundred miles. The wind and rain are strong and the road to Guanshan Mountain is still long. Whether a political party can grow up from suffering, rise up from suffering, and remain sober when winning can best show whether it is mature. Over the past century, our Party has always maintained the sobriety of "half a hundred miles away", kept in mind its original mission, carried forward the fine style of modesty, prudence and hard work, and responded to various risks and challenges on the road to rejuvenation with a strong sense of hardship and risk. At the moment when the War of Liberation was basically won and New China was about to be born, Mao Zedong earnestly warned the whole party that "to win nationwide victory is only the first step in the long march", and demanded that "two musts" be kept in mind and "sugar coated bombs" be guarded against. After the reform and opening up, in view of the complacency that some party members and cadres have nurtured, Deng Xiaoping pointed out with great sincerity that "the problems after development are no less than those without development" "Consolidating and developing the socialist system still needs a very long historical stage, and we need several generations, more than ten generations, and even dozens of generations to work tirelessly, and we must not take it lightly." Half a hundred miles is a hundred miles away, but the second half is difficult. Realizing the great cause of national rejuvenation is like running a "marathon", which is a historical relay race. After several generations of hard work, especially the great changes in the past decade of the new era, the cause of the Party and the country has made all-round breakthrough progress, providing a more perfect institutional guarantee, a more solid material foundation, and a more proactive spiritual force for the realization of the great rejuvenation of the Chinese nation. Today, we are running vigorously on the track of national rejuvenation. We have never been so close to the dream of national rejuvenation. At the same time, it should be noted that the most difficult part is the second half of the journey, and the most difficult part is to reach the target
