To celebrate the 100th anniversary of the founding of the Communist Party of China, let left-behind children in rural areas accept the baptism of the red culture, strengthen the sense of historical mission, and deepen the feelings of patriotism, the teachers and students of the social practice team of SDAEU, written missions with actions, carried out education and assistance activities for left-behind children for 20 days in villages of Heze, Shandong, to popularize the "Four Histories"(history of the Party, history of the new China, history of reform and opening up, history of the development of socialism) education, promote the red culture, practice the spirit of volunteerism, and promote rural education.

Teachers and students of the social practice team carried out the "Learn Four Histories Lessons together", "Draw Party History and Respect the Party" children's paintings, "Sing a red song to the Party", watching red movies, telling red stories to carry out red education in depth, led local children to learn history with practical actions, pay tribute to the martyrs, and be grateful for the age.

In the meticulous explanations by the teachers and students of the team, the children earnestly studied history of the Party, history of New China, history of reform and opening up, and history of socialist development. They further realized that history is the best textbook. Only by studying history can we know the question of where we come from and where we will go in the future.

This series of "Four Histories" education activities promoted the core values of socialism, promoted the spirit of patriotism, and guided the children to establish lofty ideals, cultivate fine morals, and strive to grow into a newcomer of the era who can take on the responsibility of national rejuvenation.
