This year marks the 70th anniversary of the founding of New China. In the seven decades since then, China has made remarkable achievements and moved closer to realizing the Chinese Dream of national rejuvenation. To stay true to its mission of realizing the Chinese Dream, the Communist Party of China needs to apply Marxism according to China's actual conditions.

Since the 18th CPC National Congress, the CPC Central Committee with General Secretary Xi Jinping as the core has been promoting the cause of the Party and nation by applying Marxism to China's real conditions. In this regard, Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era is a great contribution to Marxism.

Marxism is a practical, scientific, ever-developing and open theory, which not only highlights the social laws of development but also prompts people to make efforts to build a better world. Since its establishment, the CPC has led the Chinese people to many victories, by applying Marxism to solve real problems and promote the localization of Marxism.

Led by the Party, the Chinese people emerged out of thousands of years of feudalism to build people's democracy through the New Democratic Revolution; China changed its destiny by moving toward prosperity during the socialist revolution and construction period; and the nation stood up by becoming prosperous and strong during the reform and opening-up as well as socialist modernization period.

The reason the CPC could achieve these unprecedented and arduous tasks is that it followed the scientific theory of Marxism, and continuously enriched and developed Marxism both in theory and practice.

Since the 18th Party Congress, the Party has solved many long-term, outstanding problems under the strong leadership of the Party Central Committee, and China has made many achievements in the economic, political, cultural, social and ecological fields under the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, which is the latest addition to Marxist philosophy in China.

Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era makes clear what kind of socialism we should adhere to and develop in the new era, and how we can adhere to and develop socialism with Chinese characteristics.

It also advances a series of major creative and people-oriented arguments, which manifest the power of Marxism and the value of scientific socialism.

Xi's thought writes a new chapter in Marxism, and serves as a guide to better apply the basic principles of Marxism to China's actual conditions. In other words, it is a milestone in the process of Marxism's localization in China.

President Xi Jinping has stressed that Marxism is the basic guiding ideology of our nation and Party. So we should always and under any circumstances adhere to Marxism.

The fundamental reason Marxism has been our guiding philosophy for the past seven decades is that the Party has organically combined the adherence to Marxism with the development of Marxism, and continuously promoted the localization of Marxism in China.

So in the new era, we should review Marxism's development in China on a broader scale, continuously develop Marxism and further promote the localization of Marxism in China.
