History will leave valuable experience and important enlightenment to future generations. China has always attached importance to and is good at summing up historical experience, seeking laws and discovering science from it, and providing reference for future development. The party summarizes the great achievements and historical experience of the century-long struggle, with the aim of making all party comrades understand why they succeeded in the past and how to protect the fruits of victory and continue to succeed in the future. This year, China experienced major tests such as epidemic situation and flood control, and always adhered to the people-centered development thought, which continued the excellent quality and valuable experience of the older generation, and laid a solid foundation for overcoming challenges again and again. The wealth contained in history lasts forever. Even in the new era, it can still be an innovative "booster" for the progress of human civilization, thus further improving the ability to analyze and solve problems by using scientific theories, and always ensuring that party organizations can retain their ability and confidence in self-innovation under the difficult challenges of the new era, thus making China always at the forefront of the world.
