Liu Naihe studied and worked beside Chen Yuan for more than 30 years, and always took care of and helped Chen Lao as his unshirkable responsibility. Especially after the adjustment of departments, Chen Lao became the president of Beijing Normal University, and organizationally Liu Naihe served as his full-time secretary. At that time, Chen Lao was over 70 years old, so besides helping Chen Lao's administrative work and academic research, it naturally became Liu Naihe's job to take care of Chen Lao's daily life. In order to take care of Chen Lao, Liu Naihe gave up his family's family happiness. Even though he was with Chen Lao on holidays, he didn't spend a New Year's Eve in his home. Liu Naihe's selfless care made Chen Lao very moved. He once said, "If you get a bosom friend in this life, you will have no regrets." . Later, I repeatedly said emotionally to Liu Naihe: "Without you, I can't live to such a big age!"
Chen Yuan is not only the president of Beijing Normal University, but also the director of the Second Institute of History of China Academy of Sciences and a member of the Standing Committee of China People's Congress. His daily work and social activities are very heavy. As an assistant, Liu Naihe undertook most of the work. Many of Chen Lao's speeches and articles were drafted by Liu Naihe, and she often imitated Chen Lao's handwriting to write pen and ink banners to meet the demands of all walks of life. This is an open secret in Beijing Normal University, but Liu Naihe never boasted.
When Chen Lao was alive, Liu Naihe's job was to work and rest with Chen Lao. 197 1 year later, Liu Naihe can arrange his own time. With Liu Naihe's profound knowledge and superb skills, if he studies wholeheartedly according to his own wishes, he will be unique and achieve more outstanding achievements. But for the sake of the great cause of cultural and educational construction in the motherland, she has completely forgotten her personal name and interests. As Professor Li Xiusheng, director of the Institute of Ancient Books of Beijing Normal University and a famous scholar, said, "She has few personal goals in academic work, and she has her own topics to study. However, when an academic institution or individual asks her to make suggestions on a project plan, a book or an article, whether in the name of a consultant or without any name, she will do her best. Sometimes she writes longer opinions than the articles she reads. " (Li Xiusheng commemorates Mr. Liu Naihe)
Liu Naihe has a strong sense of the times and social responsibility. After the Third Plenary Session of the Eleventh Central Committee, Liu Naihe made outstanding contributions to the construction of socialist culture in the new period. "1979, Liu Naihe participated in launching the China Historical Literature Research Association, and served as vice president and president successively. In the past twenty years, she has traveled all over the country with members of the society, digging up local historical documents, discussing the history and culture of rural countries and promoting the construction of local spiritual civilization, regardless of her low back and leg pain. Especially since 1989 became the president and editor-in-chief of Historical Literature Research, Liu Naihe spared no effort to build the Society into a first-class academic group with high reputation at home and abroad. In the past ten years, she has led all the members of the Society to travel all over the motherland, and has successively carried out academic activities with the theme of local history and culture in Jiading, Shanghai, Shantou, Guangdong, xi 'an, Shaanxi, Hohhot, Inner Mongolia, Nanchong, Sichuan, Zhumadian, Henan, Guiyang, Guizhou, Leping, Jiangxi and Suzhou, Jiangsu. These academic activities have had a profound and lasting impact in various places and effectively promoted the construction of socialist spiritual civilization in the local area.
