1984 summer vacation，Two first-year graduate students and I used the holidays to investigate the Silk Road。We depart from Beijing，via Xi'an、Tianshui、Lanzhou、Yongjing、Wuwei、Zhangye、Jiuquan、bet365 sportsbook review，Stop and go along the way，Arrived at Mogao Grottoes in late July。At that time，bet365 sportsbook review’s administrative system is county，There is no airport or train station yet。We got off the train at Liuyuan Station，Transfer to bus to bet365 sportsbook review。The county is basically composed of bungalows built with adobe，Only the county party committee guest house is a three-story building，Appears to stand out from the crowd，It is the best building in the city，Of course it is also the best hotel。Before going to Mogao Grottoes，We stayed one night at the County Party Committee Guest House in bet365 sportsbook review。

一

At that time，Researchers from the bet365 sportsbook review Academy mostly live in the staff dormitories in front of the Mogao Grottoes，The three of us took the letter written by Teacher Ning Ke to He Shizhe and Shi Pingting and went to the dormitory to visit them。The two teachers warmly received us。What shocked me，The desk in their dormitory is made of adobe。Learned from chatting with them，You can’t eat vegetables here for three months in winter，And the sky is often windy and sandy in winter。I grew up in the countryside of Beijing，In the 1950s and 1960s，Although we sleep on an adobe kang，The tables and chairs used at home are also relatively simple，Sometimes even "missing arms and legs"，But at least they are all made of wood。As for winter vegetables，By 1984，There is always some Chinese cabbage。So，When I saw the simple living conditions of the two teachers，Listen to them talking about the harsh natural conditions，My soul was indeed greatly shocked！But the two teachers didn’t think it was hard，But calmly。They use ease、Tell us the above situation in a plain tone，No complaints，Give me sincere respect for them。

Because bet365 sportsbook review are not many guest houses in Mogao Grottoes，Generally not open to the public，And we hope to live in the mountains and visit，So as not to waste time traveling to and from the county every day。Teacher Shi took us to the guest house，Help us contact and complete check-in procedures，Then take us to the reception department，Specially remind them: these three graduate students are on professional inspection，Not an ordinary visit。Teacher Shi not only won us the treatment of professional inspection，We also secured several special caves for us that are rare to see during ordinary visits，And asked the reception department to assign us a better guide。

At that time，Brother Ning Qiang just graduated from the History Department of Sichuan University and soon worked at the bet365 sportsbook review Cultural Relics Research Institute，The institute arranged for him to work in the reception department for half a year，To get familiar with the cave。The reception department arranged for Ning Qiang, who has a professional background in history, to explain to us。Actually，We didn’t know much about Mogao Grottoes at that time，Said it was an inspection，In fact, there is not much difference from ordinary visitors，Everything I heard was basically new knowledge。But because Ning Qiang’s undergraduate degree is level 79 like me，And they are all history majors，So we feel closer as soon as we meet。In his explanation, he also deliberately emphasized images related to history such as "Pictures of Farming in the Rain" and "Pictures of Hu Shang Encountering Robbery"，In order to let us understand the important value and significance of bet365 sportsbook review Grottoes to historical research。

During the visit to Mogao Grottoes，We also met Teacher Sun Guozhang from the Chinese History Museum (merged into the National Museum of China in 2003)，She graduated from Peking University majoring in archeology，Worked in Mogao Grottoes for ten years，Very familiar with caves。Later，Let’s visit the cave with Teacher Sun，Lectured by Ning Qiang，Teacher Sun added。Because Teacher Sun is an old man from the bet365 sportsbook review Academy，The dean approved many special holes，We all watched it too。Visiting Mogao Grottoes for the first time，Let professionals explain，I also visited a lot of special caves，These are all given by Teacher Shi。

　September 1999 to September 2000，I checked the bet365 sportsbook review documents at the British National Library in London，Working place is the Oriental and Indian Reading Room of the library。This reading room is very big，There are several rows of large reading tables and comfortable seats，Each reader has a power plug and reading light。In addition，There is a row of small research rooms with transparent glass on one side of the wall in the reading room，The area of ​​each research room is about four to five square meters，There are two chairs and a relatively large table。Users can place books on open shelves in the reading room、Borrowed books and own books、Put the information inside，You can ask the staff to lock the door when you are away，There is no need to go through the borrowing and returning procedures every time like reading at the reading desk。Because the British National Library gave me the title of Researcher，So I was given a research room，The number is 36。This small single room brings a lot of convenience to my work，I basically go to the reading room as soon as the library opens every morning，I didn’t leave until it closed in the evening。

About one day in early 2000，I am working in the research laboratory，Wu Fangsi, leader of the Chinese section of the British National Library, and Qin Siyuan, staff, brought Dean Fan Jinshi and teacher Shi Pingting to the reading room。They are a group of five，With Chen Qiling, Vice Governor of Gansu Province、Ma Wenzhi, Director of the Provincial Cultural Relics Bureau、Vice Governor’s Secretary Zhang Zhongxu and Fan Jinshi、Two teachers Shi Pingting。They came to London to inspect the lost bet365 sportsbook review documents and bet365 sportsbook review silk paintings and other cultural relics。The English-Illustrated Chinese team also arranged a public lecture for Dean Fan，Hosted by Wu Fangsi。The Chinese team attaches great importance to the arrival of Dean Fan and Teacher Shi and their delegation，Specially arranged to grow up in Beijing as a child、Qin Siyuan, who can speak fluent Chinese, accompanied them to visit London。

I had been in London for more than half a year，I also often accompany scholars from China to visit London，So I am very familiar with the main attractions in London。Foreigners traveling to London，Of course the museum is a must-see，In addition to the famous British Museum and National Gallery，There are also many professional museums。Outside the museum，The landmark attractions in central London include Trafalgar Square、Buckingham Palace、10 Downing Street (official residence bet365 sportsbook review British Prime Minister)、Westminster Abbey、Big Ben、Congress Chamber、Thames、Hyde Park、Oxford Street and Chinatown, etc.。

But when we asked Teacher Shi and his party what attractions they had visited，Discovered except for the British Museum and the National Gallery，They have never been to most of the other landmark attractions。They also told me，Although Qin Siyuan is fluent in Chinese，But I don’t know the way，Always looking for the wrong place。This reminds me of when I first came to London，Another staff member of the Chinese team, Ge Han, came to pick me up at Heathrow Airport，Also on the wrong track。Originally from Heathrow Airport to where I live，You can get there directly by taking the subway from the airport，Although there are many intermediate stations，But no need to transfer。Ke Gehan took me to drag the huge suitcase，Not only did I change to the subway in the middle，And later changed to a taxi。I still don’t understand how Ge Han turned a straight line into a zigzag route。Compared with Ge Han，bet365 sportsbook review doesn’t matter if Qin Siyuan often takes the wrong path，Looks like Londoners are lost in the city they live in，Not that unusual。

In order to prevent Teacher Shi and his party from leaving any regrets，I offered to accompany them for a visit the next day，Take them to see all the major landmarks they have not been to yet。Because they live in a hotel next to the British National Library，I made an appointment with them to meet bet365 sportsbook review hotel lobby at eight o'clock the next morning。

There was an episode that night。After eight o’clock in the evening，Dean Fan and Teacher Shi called me，Maybe I want to confirm the arrangements for the next day。Because I have to make the most of the library’s opening hours during the day，So I usually arrive as soon as the library opens in the morning，I didn’t come out until the museum closed in the evening。In this way, exercise can only be arranged in the evening。At that time，I walk for more than an hour every night to exercise。Just when I was out exercising，Teacher Shi and the others called。The phone in my room is a recording phone，If no one answers after three rings，There will be an English reminder that the owner is absent，You can leave a message after hearing the "beep" sound。I’m back from exercise，I found that the red light of the phone recording is flashing，Open recording，I heard the conversation between Dean Fan and Teacher Shi。“Why doesn’t he answer the phone?？He won’t leave us alone tomorrow..." I guess the two teachers still don’t understand the function of the recorded phone call，The chat between the two of them was recorded by a recorded phone call。I will call you back immediately，But no one answered。They may have fallen asleep，Perhaps because you are abroad and don’t dare to answer the phone rashly。There were no mobile phones at that time、WeChat and other contact information，The landline cannot be contacted，We can only talk about bet365 sportsbook review when we meet the next morning。I think，As long as they can see me on time the next morning，The misunderstanding will naturally be resolved。

The next morning，After I had breakfast，Get to the hotel lobby before eight o'clock。Eight o'clock，bet365 sportsbook review and his party also went downstairs to the lobby，I explained to the two teachers that I didn’t receive a call from them last night because I went out to exercise，And tell them that the main attractions are in central London (Zone 1)。

London’s zoning is similar to Beijing’s ring line，The first area is the central area，District 2 is equivalent to the area between the Second Ring Road and the Third Ring Road，District 3 is equivalent to the area between the 3rd and 4th Ring Road，The fourth district is outside the fourth ring road。Based on our experience of many tours，You can visit all the scenic spots in District 1 by walking in one day。I didn’t expect bet365 sportsbook review，They want to take a taxi tour。London taxis are very expensive，A medium-distance journey costs at least £30，About half a month’s food expenses at that time。So，I only took a taxi once in my year in London，Because there is something particularly urgent。For us international students and visiting scholars，Taking the subway is actually very expensive。At that time，We basically rely on walking in District 1 of London，To District 2、District Three、Use public transportation only in places far away from the fourth district。Accompanying Teacher Shi and his delegation on their trip to London was my second time taking a taxi in the UK。

We first went to Trafalgar Square，There are flocks of pigeons there，If visitors scatter some food such as millet on the ground，The pigeons will immediately fly to the head bet365 sportsbook review person、Shoulder，Everyone who visits the square must take a souvenir photo among the pigeons，Enjoy the wonderful feeling brought by the pigeons。So，This is also called Pigeon Square。

The second attraction is Buckingham Palace，This is the main residence and office of the King of England in London。Buckingham Palace is generally not open to the public，In most cases，Tourists can only take photos outside the palace fence。Every morning，The Royal Guards in classical costumes held a changing of the guard ceremony，This is the best representation of British culture，But unless the time is specially arranged，bet365 sportsbook review difficult to meet tourists who want to see several attractions in one day。I have been there many times，Only encountered once。

The third attraction is Westminster Abbey。This church is not the largest church in London，But because bet365 sportsbook review the place where kings were crowned and royal family members held weddings，So bet365 sportsbook review regarded as the holy place and the highest status church in Britain。

The fourth attraction is No. 10 Downing Street，British Prime Minister’s Official Residence，This place is not open to the public either，You can only look in from outside the big iron gate，You can take photos with the guards，The guards will cooperate in a friendly manner。Because bet365 sportsbook review is a constant flow of traffic in Downing Street，The sidewalk is not wide either，Plus bet365 sportsbook review are so many tourists，So I can’t stay here for long，Basically, you have to leave immediately after taking pictures，Give your seat to other tourists。

Go along No. 10 Downing Street，You can see another London landmark at the crossroads - Big Ben。Big Ben is the nickname of Westminster Clock Tower，bet365 sportsbook review the symbol of the City of London and the symbol of the United Kingdom。The Big Ben on the clock tower is huge and gorgeous，Heavy 13.5 tons，The area of ​​the four clock faces is about two square meters，bet365 sportsbook review a famous ancient clock in London。Go to the foot of Big Ben and then go forward，The Thames, the mother river of Britain。Standing on Westminster Bridge，You can enjoy the rolling waves of the Thames and the passing ships。Returning from Westminster Bridge，Not far away is the British Parliament Chamber。The British Parliament Chamber can be visited，If you encounter a congressional debate，You can also listen。I have been there several times before，These are empty conference halls。But this time we encountered a debate in Congress，We sat in the gallery and watched the debate。

Coming out of the Congress Chamber，We took a taxi to Hyde Park again。Hyde Park is the most famous park in London，Very large area，It takes at least half a day to make a full circle。London’s parks are mainly grassy areas，There are a few trees，Not like a Chinese park，Built with many landscapes。It’s rainy in London，No need to water the grass either，It grows very lushly。Actually，Most Chinese people go to Hyde Park to see the famous “Speakers’ Corner”。There are always people giving various speeches there，Some people will listen，Some even no one listens。I’ve been there several times，I found out that some people “give speeches” there every day，bet365 sportsbook review said to be a mental patient。

Walking around Hyde Park，We took a taxi to Chinatown again。London’s Chinatown not only has many Chinese restaurants and food，bet365 sportsbook review also a shopping place for Chinese people。There were not many Chinese in London at that time，bet365 sportsbook review difficult to find food and ingredients with Chinese characteristics in ordinary supermarkets and stores。For example, tofu，At that time, it was only available in Chinatown。There are not only various specialty restaurants and table meals，There are also fast food that can fill you up for just two and a half pounds，Usually make a few meat and vegetable dishes and staple food，Guests can choose as they like，Eat according to your stomach。

Our last stop is Oxford Street，Oxford Street is lined with various shops，Various souvenirs，There are also clothes、Shoes、Hat and other various products。I remember，bet365 sportsbook review was already evening when we arrived at Oxford Street，Everyone chose some souvenirs or merchandise。

Back to the hotel，Teacher Shi and his entourage all highly praised my "tour guide"，Everyone said that this day’s harvest was greater than what they had achieved bet365 sportsbook review previous few days。Can satisfy them，I am also very happy。

Teacher Shi has broad academic interests，Involved in many fields of Dunhuang studies。In my opinion，In Teacher Shi’s achievements on Dunhuang studies，The "New Compilation Index of bet365 sportsbook review" took the longest time、The most force、The greatest contribution，Its influence even exceeds any monograph on Dunhuang studies，Can be regarded as Mr. Shi’s masterpiece。But regard a reference book as a masterpiece，And comment as above，It is inevitable that some people will have questions，Therefore a brief explanation is needed。

Let’s talk about the longest time first。Teacher Shi began to revise the "General Catalog Index of bet365 sportsbook review" in the early 1960s.、Problems in inscription and interpretation，It was not until 1999 that the "New Compilation of the General Catalog Index of bet365 sportsbook review" was completed with the help of assistants，It took nearly 40 years。We often say that it takes ten years to sharpen a sword，I am willing to sit on the bench for ten years，Teacher Shi has been doing this for decades，Wu Wu Poor Year，Being a role model for future generations。The concept of time in the past 40 years，Not only does it take the longest time among Teacher Shi’s works，In all the treatises on Dunhuang studies，It should also be included in the longest list。

Besides, the most force is used。From the "Preface" of "New Compilation of the General Catalog of bet365 sportsbook review"，Teacher Shi from the 1960s to the late 1990s，Working on the revision of the "General Catalog Index of bet365 sportsbook review" has always been a "daily job"。If you pay attention to Teacher Shi’s academic resume and academic achievements，We will find out，Cataloging work is always the most labor-intensive work for Teacher Shi。For example，During my visit to Japan in 1989，Teacher Shi uses the unique data conditions of Dongyang Bunko，The work I do every day is to revise the "Stein Tribulation Sutras" part of the "General Index of bet365 sportsbook review"，Work records are filled with six large notebooks，It can be said that there are enough manuscripts。

About the contribution of "New Compilation of the General Catalog Index of bet365 sportsbook review"，Can be divided into four aspects。Firstly, many naming errors in the "General Catalog Index of bet365 sportsbook review" have been corrected。Including the names of Buddhist scriptures that Teacher Shi himself searched and researched in the "Taisho Zang" and the names of documents that the academic community has successively researched。Secondly, many new entries have been added。Because most of the Dunhuang posthumous documents are manuscripts，Many volumes with the same number contain many contents of completely different nature，But when compiling the "General Index of bet365 sportsbook review"，The nature and names of many documents cannot be determined，The names of this type of documents are ignored in the "General Index of bet365 sportsbook review"。The "New Compilation of the General Index of Dunhuang Posthumous Scripts" has added many documents whose nature and names have been verified by the academic community after the publication of the "General Index of Dunhuang Posthumous Scripts"。Third, the "Explanations" attached to the "General Catalog Index of bet365 sportsbook review" and the "Explanations" of some documents have been revised and supplemented。The fourth is in the description style，Added items such as "first question", "original question", "complete from beginning to end", "excellent questions in the middle"，Provides more reference information for readers to understand the document。Because the above aspects involve a lot of work，So the "New Compilation of the General Catalog Index of bet365 sportsbook review" should also be Teacher Shi's greatest contribution to the academic world。I think，Every scholar who has used this book will agree that Teacher Shi is the hero of the "General Index of bet365 sportsbook review"，For the cataloging of Dunhuang posthumous documents，It is said that "there must be such people in history"，It shouldn’t be an exaggeration。

In the academic evaluation system at home and abroad，Compiling reference books is a job that is not valued by others，Not only do few people regard reference books as masterpieces，In promotion and award activities，It is difficult for reference books to have a place。But in the field of Dunhuang posthumous documents and other unearthed documents，Many reference books actually have high academic content。In the field of Dunhuang studies，At least the three reference books "New Compilation of General Catalog Index of bet365 sportsbook review", "Dunhuang Dictionary" and "Dunhuang Popular Dictionary" are of high academic value。As far as the cataloging of Dunhuang posthumous writings，Because naming a document involves understanding the content and nature of the document，So the compilation process is also an arduous research process。And because cataloging needs to process the name of each document encountered，So its compilation is more difficult than writing a monograph。Because when doing special research and encountering documents that you don’t understand, you can avoid them，But not cataloging，We must build roads over mountains and build bridges over water。This is one of the reasons why many people are discouraged from cataloging work。

The cataloging work of Dunhuang studies is extremely difficult，It is a difficult but not necessarily a thankless job，But its influence is far greater than any academic monograph。Like "New Compilation of the General Catalog Index of bet365 sportsbook review"，It is not only a must-have book for people in the industry，It is also a must-read book for outsiders to understand this subject，So its readership and coverage are far larger than any other monograph on Dunhuang studies。As a practitioner of Dunhuang Studies，There is a book like this，Enough to become an internationally renowned Dunhuang scholar。The above are the reasons why I regard "New Compilation of the General Catalog of bet365 sportsbook review" as Master Shi's masterpiece，I don’t know if Teacher Shi agrees？

"The New Index to the General Catalog of bet365 sportsbook review" has been published for more than 20 years，Since its publication, this book has become an upgraded version of the "General Index of bet365 sportsbook review" and replaced it。I think，Before the new general catalog of Dunhuang posthumous writings is released，It will still be a must-have book for scholars within Dunhuang studies、A must-read book for laypeople to understand Dunhuang studies。
