Gu Jiegang (1893-1980) and Fu Sinian (1896-1950) are also in the field of ancient Chinese history research，Two people learned about、Works, etc.、Fame and Forest，Make outstanding contributions to the research of traditional culture in my country，Affecting generations of scholars。The two are students of Peking University，The current understanding of Gu Jiegang to Fu Sinian has a total of 24 seals，The first was December 18, 1918，The last one was June 11, 1940，The relationship between the two people during this period is more closely。Examination of the study spirit in its letter is important for us to understand Gu Jiegang in all aspects。The academic spirit it contains is mainly reflected in the following aspects。

　　bet365 Play online games Autumn 1918，Fu Sinian and others launched the establishment of Xinchao Club at Peking University，Publish "New Wide" magazine，Specialized to introduce modern western trend、Criticizing Chinese modern academic and social issues as the main purpose，Gu Jiegang is one of the first batch of members。Gu Jiegang mentioned the magazine improvement problem in the letter on August 11, 1919，The important proposal is to pay attention to social conditions，"We want to destroy the old society，The situation of the old society must be proposed，But there is no special book for this situation，No reference research can be done，So I want to add a door，Everyone、Each thing、All industries、Humans and customs of all classes are collected，Fortunately, the sales bank gradually broad，This kind of thing is only a straight book，No need to send a discussion，Forgive readers are easy to submit "。Letter on February 21, 1919 mentioned that academic research should pay attention to "transforming society"，Gu Jiegang believes that "the concept of life is the essence of creating thought"，So do magazines、The purpose of learning is to "transform the mind"。He supports the new culture movement，Pay attention to promoting cultural activities to the public。

　Second, a wide range of learning methods.In the letter on December 18, 1918，Gu Jiegang put forward his own view on the academic style of the "New Wide" magazine: "Each member has drafted the topic made by each member，Report each other: If the thought of a certain B thought of the title of a certain A，You can inform the meaning of a certain B，If you are in favor，One more positive reasons，If a certain armor is opposed，You can also refute this，One more reason for the opposite。"This method is the wisdom of everyone，Visitor beneficial insights，The benefit is "Compare one person alone，or flip the book around，More benefits "。The most important manifestation of the most important thing is to take advantage of it、Learn from each other，"To take the long of others，To make up for my generation's short，Take the thought of others for a certain problem，Come to compare the thoughts of my generation for this problem "。Facing the situation of each school in the society，Gu Jiegang said: "I think today’s academic industry，The mind that should not be existed in the whole side，Strive for a victory for you，All right problems。Short short take long，Interactive entertainment。"In the letter on February 21, 1919，Gu Jiegang once again mentioned those scholars who criticized magazines，In his opinion，These "people who refuse to obey" are the most respected，Because these comments are "where knowledge is connected，The most convenient place to take advantage of the strengths and shortcomings "，It is good for everyone。

　Third, a sincere academic attitude.Writing in a letter on December 18, 1918，"New Wide" magazine formulate academic specifications，Gu Jiegang put forward the request of "integrity"，Specific implementation can be divided into three articles: (1) Do not post; (2) Do not save it to oppose people; (3) Do not face lying。"With sincere and strong feelings，Moving Society "，As long as "attitude is warm，Do not refuse people beyond thousands of miles "，can produce good effects。

　　Fourth, humble and cautiously seek knowledge.Gu Jiegang was born in Shuxiangmen's home，Read the "Four Classics"，Deep in traditional cultural heritage，In 1915, the 20th volume of the "Test of the Qing Dynasty" was completed，A deep understanding of the Qing Dynasty academics。But Gu Jiegang never boasts。December 18, 1918: "I tasted it in the past，I thought I have not yet indeed rooted，Bright concept，No fine test in history，It will be announced in society。I am far from this realm now ... I have a bad knowledge，So there are many problems in my heart，Although there are some realm，But it's a bit blurred and blurred、Capital，I dare not say that it seems like this，I dare not say that it is like this ... I will ask for benefits with an open mind; if anyone refutes me，I decide to abandon the emotional feelings，Excellence in Chengxin。"" In the letter on February 21, 1919，He said that he has no talent，Poetry Classics，and ask Fu Sinian to help modify: "You have been a good article for people and mountain encounters，I made two non -rhyme poems that people and Shanli the day before yesterday，Although the scene is true，I have no poems，Can't make him poetic! Please write it out，You said okay，Log in with me -must be the last position -you said not good，Just put it up。Thousands of do not be polite —— such as willing to change the feeling。”

　　Fifth, the academic method combined with the combination of criticism.Academic standards for journal，Gu Jiegang proposed in the letter on August 11, 1919 to propose the method of "let readers be more criticized"。On January 7, 1927，His request to post Fu Sinian's letter，And specifically emphasized the importance of criticism: "So my brother published text，Not afraid of it shallow or error，Just afraid of it narrow，Can't be criticized by others。Letter I give me a letter，Although not complacent，But how many problems can be caused，How many people are caused to discuss or attack，This is a good thing。"Gu Jiegang believes that through readers' accusations and criticisms，can find out the loopholes of the article，and take this test、Modify，Completion of academic achievements: "We often publish words，Naturally, some people come to talk about，You can also modify your opinions again and again，Make it closer to facts。There is another good impact，Let the readers see that we modify our opinions again and again，​​Materials to add more time，The desire to stimulate their knowledge，Can seek knowledge in normal methods。”

　　Sixth, new historical concepts and international vision in college.In the letter on August 11, 1919，Gu Jiegang asked Fu Sinian, who was about to go to the UK: "When you go to the UK，I often buy excellent historical books for me，Makes us a clear historical concept that we first have a clear history。"" In the letter on February 21, 1919，Gu Jiegang hopes that Fu Sinian is published in an article，"Several articles of describing the outlook of various western philosophers，Examples of "Iphali" with Mr. Ibu "。This shows that Gu Jiegang has begun to pay attention to foreign history research，And want to use Western historical methods to study Chinese history。Because it is to break the old academic norms -the mode of the history of the history，So he values ​​personal notes、Fang Zhi and other non -traditional literature。From Gu Jiegang's view，These are new historical materials engaged in new historical research。

In the letter on June 27, 1927，Gu Jiegang showed the idea of ​​going to Japan，His major academic achievements in Wang Guowei studying in Japan are envious。At the end of 1936，Harold William Vazeille Temperley，1879-1939) At the invitation of Yingkang Chuanyi to come to China，Tian Bolie's purpose of coming to China，Except for travel、Outside lecture，It also has the mission of contacting Chinese historical groups to participate in the International History Society。mid -November，Tian Bolie arrives in Peiping，December 1，Gu Jiegang, Director of the History Department of Yanjing University、Director of the Political Department of Peking University Tao Xisheng went to the Beijing Hotel in Tian Bolie，Further discussions on China ’s joining the International History Society。In the letter on December 22, 1936，Gu Jiegang co -branded Tao Xisheng expressed to Fu Sinian the idea of ​​"the establishment of a general meeting in Nanjing" and "Beiping's establishment of a branch"，and hope that the specific plan of the organization will formulate the organization in the spare time。It can be seen through the ideas and measures of Gu Jiegang above，He already has an Bet365 app download international vision of historical research。

　　Seventh, patriotism in school.Gu Jiegang is a very traditional Chinese intellectual，Pay attention to family、Friendship，For family、Friends are very concerned。Many descriptions in the letter、Expressing this kind of care。For example，Whether you want to yourself，I want family，Thinking of the country，I feel that the future is vast，I can't be the master。"His patriotic feelings are also manifested in studies，Gu Jiegang wrote in the letter on October 23, 1935: "Brother founded the Yugong Society，Issuing "Yu Gong Half Monthly"，is the expansion of your editor's "History of the Northeast"，I hope that the concept of the readers will regain the homeland，A solid foundation for nationalism。"1931，Japanese invaders launched the "September 18th Incident"，Invasion of Northeast，At the time of national crisis，Fu Sinian wrote the book "Northeast History" with other scholars，Historical facts with iron proves that the Northeast has been an indispensable part of Chinese territory since ancient times。Gu Jiegang needs to start paying attention to the history of the border according to the needs of the times，Defend national interests from history and morality。Gu Jiegang advocates instilling patriotic thoughts from students in academic research，The letter on March 6, 1936 records: "The most important thing is the sound of thought，Tell him all the historical facts that the children should know，Speak on the national nation of China at the same time，The heart of children's patriotism and love，and suggest that children know how to create new valuable history。”

Gu Jiegang to Fu Sinian's 24 books contains the personality of the two、Habits and social interaction。As a historian，In addition bet365 Play online games to the spirit of academic letter，There is a typical life atmosphere、Homeland feelings and characteristics of the times，With obvious purposes of the world。Gu Jiegang is in the old and new society alternate，It is an important pioneer of new history，made an indelible contribution to that era。to this day，These school spirit is still worth our learning。
