Many people say，Qian Zhongshu has a very strong memory，Photographic memory。He himself doesn’t think he is that “godful”。He is just good at reading，Willing to work hard，Not only read，Also taking notes；Not only read it once or twice，I will read it three or four times，Continuously adding to the notes。So although he reads a lot of books，It’s not easy to forget either。
His habit of taking notes was developed when he was studying in the Oxford University Library (Bodleian - he translated it as 褹楼)。Because the books in the house are not allowed to be borrowed。Go there to study，Only notebooks and pencils allowed，No traces are allowed on the book，You can only memorize while reading。The first volume of Zhongshu's "Secretary of Guanjinglou" contains the following lines: "From February of the 25th year (1936)，Make an appointment with Jiang to go to the university library to study，Everyone brings a note，Lu Chao Xue Compilation、Let’s make up for the lack of three boxes，Iron painted silver hook，Thousands of false claims are bald，It’s for guidance。"The second volume has the following inscription: "Heart is like a coconut, a book of gatherings，The Golden Chamber and Green Box are not as good as anything，Feedback Gouxuan Liuzhiclaw，Forget about the future and there will be no fish。(Default question，Ji Kang wrote under the lamp with a wolf and chicken brush" These are all written with a brush，Obviously not while reading and taking notes in Shouyanlou，But after rumination，The notes written then。
Taking notes is time-consuming。Time for Zhong Shu to take notes，About twice as long as reading this book。He said，A book，Read again for the second time，You will always find a lot of oversights when you read it for the first time。The most wonderful bet365 online casinosentences，You have to read it several times before you realize it。
Zhongshu reading and taking notes has become a habit。But make it a habit，Because we have not had a stable place to live for many years，No place to store books。He loves to buy books，There are many sources of new books，But most of the books are borrowed from various libraries。He finished reading and taking notes，Just return the borrowed book，My books are often given away casually。Zhong Shu is well aware of the principle that "you cannot read a book unless you borrow it"，If you have a book, read it as soon as possible，Always take notes after reading。Countless books flow in and out of my house，All that remains are notes，So I don’t have a large collection of books at home。
Zhongshu’s notes from abroad to home，From Shanghai to Beijing，From one dormitory to another，From the iron box、Wooden Box、Carton，Even sacks、In and out of pillowcase，After several tortures，Some notebooks have blurred writing，Paper damaged。Zhong Shu always likes to read one or two volumes of Chinese or foreign notes every day，Always read wonderful fragments to me。I once wanted to repair his worn notes，He stopped me。He said: "Some of them are useless。”Which ones are useless？Is it of no use to anyone?？I didn’t ask at the time，I never thought of asking in the future。
After Zhongshu’s death，I found a lot of notes，After repeated editing，Divided into three categories。
The first category is foreign language notes (foreign languages include English、法、Germany、meaning、Spain、Latin)。Except for a very small part, Zhong Shu typed it on a typewriter with two fingers，The rest are all handwritten。The notes also include the bibliography, important editions, and the number of pages of the original text。He does not ignore academic publications when reading。Any literature related to famous writers、Philosophy、Important papers on politics，He takes notes after reading，And note the year the publication was published、month、日。Zhong Shu has freed himself from the shackles of studying bet365 online betting appfor a degree，Just read as much as you want。English Literature，He already has some foundation。He further studied French literature，From the fifteenth century to the nineteenth century and the twentieth century；Also studying German literature、Important works of Italian literature throughout the ages，Read each one carefully，And take notes diligently。This way，He laid the law for himself again、Germany、The literary foundation of Italy。later，He just reads as he sees fit。His notes，Often refer to each other，So these notebooks are difficult to organize。And I don’t understand German、Italian and Latin。It happened to be the German sinologist Dr. Mo Yijia (ProfessorDr who translated "The Besieged City".MonikaMotsch) comes to Beijing。I asked her to help me arrange it。She saw the table of contents and fragment contents，"Greedy" will take the opportunity to come to Beijing again next summer，Help me organize all the foreign language notes。One hundred and seventy-eight notebooks in total，There are still a few pages of typescript，All foreign language notes total more than 34,000 pages。
Zhongshu studies foreign literature in universities at home and abroad，Teaching at a university and also teaching foreign literature，After "Department Adjustment"，He also belongs to the foreign literature group of the Institute of Literature。But he has been sent to do other jobs for many years，Later, he was seconded to the Chinese Classical Literature Group，Never able to return to work in the foreign language group。He originally planned to write a book on foreign literature in English，Always failed to do so。Those foreign language notes，For him，It’s time to “useless”。But for those who study foreign literature，For those who study Qian Zhongshu’s works，Could it be useless？
The second is Chinese notes。He started mixing Chinese reading notes with his diary。In 1952, when intellectuals first underwent “thought remolding”，He heard that students can check the diary of "the old man"。Diary is a private matter，Not suitable to be mixed with academic notes。He used small scissors bet365 online sports betting liveto cut off part of the diary and destroyed it。This part of the note is in pieces，And they are all scattered，It takes a lot of effort to sort out。His notes，All come with their own comments，Also refer to it frequently、Mutual citations。He will write down the bibliography for future notes himself，There are also some occasional comments。Number of Chinese notes and foreign notes，Roughly the same。
The third category is "Sunday Notes"——Zhong Shu's reading experience。The Rizhao Thought started after the "thought remolding" movement。The original notebook still has smudged and cut marks。From now on, he will write various names on the letters，Such as "Ronganguan Daily Notes"、"Rong Anshi Daily Notes"、"Rong An Zhai Daily Notes"；There are also various signatures，Such as "Master Rong'an"、"Rong Anzhai Layman"、"Huaiju Jushi" etc.；Still serious about it，Stamped with various stamps。I will divide it into categories first，I realized it later，These "pavilions"、"Zhai"、"room" etc.，Only after the “department adjustment” in 1953，The small bungalow in Zhongguanyuan where my family lives (quoting Tao Yuanming's "Returning Letters" "It's easy to put your knees at ease")。Moved several times since then，Zhongshu is a place where "it's easy to settle down"，So the name of Rizha has not been changed。
Twenty-three volumes of daily notes、More than two thousand pages，Eight hundred and two points。Each item has only a number，No article。The daily letters are basically written in Chinese，There are a lot of foreign languages，Sometimes several articles are in foreign languages。No matter ancient or modern, Chinese or foreign，From the liberal arts and profound classics of the past，Go to the popular novel version，Even village slang，He all quoted each other，Comprehension，And the heart has something to gain，But this "experience" has yet to be written into an article，In order to become his work。In "Guan Zi Bian"，Experiences in the daily journals，A fully developed article。For example: "Pipe Cone Edition".Eighteen Supplementary Annotations to the Songs bet365 games best slotsof Chu by Hong Xingzu，Ninety-five pages in total，A note on reading "Chu Ci" in Rizha，Only sixteen pages have been memorized；《Pipe Cone Edition.Twenty-seven chapters of Zhouyi Zhengyi，One hundred and nine pages in total，Notes on reading "Book of Changes" in Rizha，Only one，Less than twelve pages；《Pipe Cone Edition.Sixty pieces of Mao’s Poems on Justice，One hundred and ninety-four pages in total，Two notes on reading "Mao's Poems" in Rizha，Less than seventeen pages。
Zhongshu said in the preface of "Guan Zui Bian": "... then I found out that Jian is easier to manage Dong，A glimpse of the cone finger tube，First album”、"Initially, it was planned that this collection would include "Quan Tangwen" and other five kinds of books，Sick and lazy，Don’t rush。"My experience in reading "The Complete Tang Dynasty" and other books，It’s all in the journal。He once said to me: "I at least want to write another article about "Han Yu"、An article from "Du Fu"。”These two articles，I want to be someone who is “difficult to manage directors”，Add "sick and lazy"，Not written out。Experiences in Rizal，There are quite a few articles that have not been written yet。
This large number、Foreign language notes and reading experience，Zhong Shu is “useless”。But he spent his whole life begging for stones to accumulate knowledge，For those who study other knowledge and Chinese and foreign cultures，It should be a useful legacy。I should do my best，For those who are interested in reading and seeking knowledge，Keep the notes and journals left by Zhong Shu properly。
Thanks to the Commercial Press for its willingness to scan and print all Qian Zhongshu’s manuscripts，Preserves the original appearance of the manuscript，Make it public。I believe that making it public is the best way to preserve it。I wish I could do this，"The dead are alive，The living have no shame”。
