Establishing the core position of leadership and establishing the guiding ideology are an organic integrity of dialectical unity. The principle of “Two Establishments” is the most important political achievement since the 18th CPC National Congress, the valuable experience of the CPC over the past century, the concentrated embodiment of adapting Marxism to the Chinese context and the needs of the times, and the inevitable choice for achieving the great rejuvenation of the Chinese nation. In the new era, we should adhere to the “Two Establishments”, bear in mind what is unfolding in China and the world, and uphold Xi Jinping’s core position in the Party Central Committee and in the Party as a whole. We should learn and implement Xi Jinping Thoughts on Socialism with Chinese Characteristics for a New Era and master the positions, viewpoints, and methods. We should focus on the great project of the Party building in the new era, and fully implement the mission and task of the Party in the new era and new journey.
