Qi Sihe (1907 ——1980) is the word to China. China historian. Tongren, Wuhu, Ningjin Town, Ningjin County, Shandong Province. 193 1 After graduating from the history department of yenching university, he studied in the United States and studied western history at Harvard University. 1935 received a doctorate in history in July and returned to China in the same year. He has been a professor in the history department of Beiping Normal University, yenching university and private China University, the head of the history department of China University, the head of the history department of yenching university and the head of the literature department of yenching university. 1952 transferred to Peking University history department as a professor. 1958, director of the world ancient history teaching and research section of Peking University history department. 1979 was elected honorary chairman of China World Medieval History Research Association. Qi Sihe is knowledgeable and familiar with ancient and modern China and foreign countries. He has studied the modern history of China, the history of Sino-foreign relations, the history of Sino-Western exchanges, the history of medieval world, the modern history of the world, the history of Britain, the history of the United States and the history of historiography, especially the history of pre-Qin and medieval world. Qi Sihe has been engaged in the teaching and research of China's ancient history and world history for a long time, and has opened courses such as China history, Shang and Zhou history, Qin and Han history, world medieval history, modern world history, British history and American history. He studied China's pre-Qin history and the world's medieval history, paid attention to the comparative study of China history and western history, and wrote a lot of valuable works. He is the author of The Origin of China's History, Lectures on World Medieval History and Lectures on Introduction to History. Qi Sihe often wrote some articles about history when he was in Nankai Middle School, which attracted Mr. Fan Wenlan's attention. Encouraged by Fan Wenlan, Qi Sihe entered the history department of Nankai University after graduating from Nankai Middle School.

It was also taught by Fan Lao. After studying for a year, Fan Lao said to Qi Sihe, "You like reading so much, you might as well go to Beijing. After all, Tianjin is a commercial city and Beijing is a cultural city, where there are many famous teachers. "

1928 Yanjing was just enrolling students, and Qi Sihe entered the second year of Yanjing History Department. When Qi Sihe first arrived in yenching university, yenching university's fame was not great, but he had already received considerable attention. At that time, yenching university had just moved from the old armor factory in Beijing to the new Haidian site in the western suburbs, and a large number of famous teachers gathered in the beautiful campus. Founder Si Tuleideng is determined to build yenching university into a world-class university. Mr. Hongye has just returned from Columbia University. In his view, modern China needs modern education first. Mr. Hong is engaged in history, and naturally regards history as the top priority of modern education. So, according to the American model, with his own expectations, Mr. Hong began to transform the history department of Yanjing and invited a large number of famous teachers. Before that, only Mr. Chen Yuan was a famous teacher in Yanjing. Later, Gu Jiegang, Rong Geng and others came to Yanjing one after another.

In the year when Qi Sihe entered yenching university, Harvard University also looked for partners in China. The Al King's Hall Foundation of the United States funded the establishment of Sinology Center in China. Finally, this opportunity was won over by Mr. Si Tuleideng and Mr. Hongye, and four-fifths of the funds were obtained to set up a Sinology Institute, namely Harvard Yanjing Society. The fund is managed by Yanjing, and the specific person in charge is an American, but Mr. Hong's opinion is very important.

Qi Sihe was the first student sent to Harvard by Yanjing. At that time, Yanjing could recommend one person to study at Harvard every four years, and the Harvard Yanjing Society also awarded a scholarship. Harvard requires that this person must get a doctorate within four years. If he fails, Harvard will look for such a candidate in other schools. Qi Sihe showed his historical skills as soon as he entered Yanjing. At that time, Mr. Gu Jiegang was teaching "Research on the Ancient History of China" in Yanjing, and Qi Sihe liked this course very much. Qi Sihe recalled that Mr. Gu often quoted other people's words in class, and his ideas were novel, which was especially popular with students. Teacher Gu has to write three blackboards in each class. Whenever different academic opinions are published in newspapers and magazines, Mr. Gu should guide students to express their opinions and discuss them in class, so as to inspire students' ability of independent thinking. Qi Sihe listened to Mr. Gu's class during his college years and wrote the article "Talking with Gu Jiegang about the Book of Viewing Image Makers in Yi Zhuan". 1929, the History Department of Yanda University organized the Historical Yearbook, and the task of editing the Historical Yearbook actually fell to Qi Sihe, an outsider.

Qi Sihe served as the editor-in-chief of Historical Yearbook for three years until graduation. When he graduated, his classmates wrote an inscription for him in the Yanda Yearbook: "From the group images of various schools of thought to Kang, Liang, Hu and Gu, you can see everything in learning;" Every time you read a book, you will find novel problems, especially in textual research, historical methods and Hanshu. "

Perhaps for this reason, Mr. Hongye attached great importance to him and regarded him as a candidate to study at Harvard. But Qi Sihe didn't want to go at first, because Qi Sihe's interest at that time was the history of China. He himself said, "I can achieve a lot in four years in China. What should I do in America? Do China history? There are no books there, and the professor is not as good as China. " But Mr. Hong took a fancy to him and thought that Qi Sihe would get his doctorate in four years. He advised Qi Sihe: "You should go, not only to ensure that you can get your doctorate in four years, but also to ensure that this candidate falls in yenching university. It's also good for you personally. Going to the United States to see their research methods can broaden your horizons. "

What puzzled Qi Sihe was that he didn't know what to learn when he arrived in America. He studied the history of China as if there was nothing to learn there. Mr. Hongye also suggested Qi Sihe: "You go there to study their best subjects." In 1930s and 1940s, Harvard was an important town for studying American history, and so-called "star professors" gathered. Mr. Hong suggested that Qi Sihe go there to study American history. Qi Sihe was reluctant at the time: "American history is so short?" . "Mr. Hong said:" Although the history of the United States is relatively short, they have studied it deeply. You can learn their research methods. When you come back, you can study the history of China in this new way, so as to make a new breakthrough in the history of China. "When Qi Sihe arrived at Harvard, he felt that he had a great responsibility, because it was not only related to his studies, but also to the school. So as soon as I arrived, I plunged into the library and started a "3.1 line" life. Qi Sihe's hard work was not in vain. At Harvard, even Professor Schlesinger, who was famous for his strict requirements at that time, had to sit up and take notice of Qi Sihe and spoke highly of his paper. Four years later, I got my doctor's degree and learned about the trends of international academic circles at that time. After returning to China, Qi Sihe became a professor in the history department of Beijing Normal University. Qi Sihe said: "I have been studying in a private school. I want to teach in a national school and learn about the situation there. "Qi Sihe brought back new discipline. He said that there were only two people who really studied American history in the United States at that time, including him. The other is Mr. Pi Mingju, who has been living in Hunan and is a descendant of Pi Shirui, a great scholar in Qing Dynasty. At that time, Qi Sihe not only taught in Beijing Normal University, but also in Peking University, Tsinghua and Yanjing.

Qi Sihe opened a historical theory and modern world history in Peking University. Historical theory was a new discipline in China at that time, which was highly valued. Qi Sihe used the methods he learned in the United States, that is, studying China and studying foreign countries, and established his own unique style of study, forming the academic characteristics of "comparative history". In the second year after Qi Sihe returned to China, Hu Shi had planned to hire Qi Sihe to teach in Peking University. After talking with Qi Sihe, Qi Sihe also hopes to go to Peking University. Qi Sihe resigned from Beijing Normal University and decided to accept the invitation of Peking University, but then the July 7th Incident broke out. Because Qi Biting (the first female teacher's principal in Zhili, Tianjin) moved to the rear area with the school, Qi Sihe had to stay in Beijing in order to take care of her mother in Tianjin nearby, and she didn't want to teach in a school under Japanese rule, so she returned to Yanjing to teach, but Peking University failed. It was not until 1952 that Qi Sihe arrived at Peking University. When Qi Sihe returned to Yanjing, he moved to Yanjing from an alley next to Liulichang. From 1937 to 194 1 pearl harbor incident, he first lived in Bingshi Hutong near Yanjing, and then at No.56 Yannanyuan. After Pearl Harbor, he moved out of Yanjing. In order to make a living, Qi Si and a group of professors who didn't want to have sex with the Japanese all went to China University to teach.

1946 Yanjing resumed school, planned by Mr. Hongye. At that time, Mr. Hong's residence in the newly opened road in the city became the contact center of Yanjing people, and he constantly studied the plan of resuming school. That year, Qi Sihe and his family returned to Yanjing and moved into No.51,the largest house in Yannan Garden at that time, because Qi Sihe had a large collection of books and was the dean of the Humanities College at that time. Starting from 1949, the school began to adjust the house. From 1949 to 1952, Si Qi and his family moved around Yannanyuan and finally settled at No.66 Yannanyuan. That yard used to be where Mr. Bing Xin lived.
