Suddenly I have heard that Professor Ditman of Cambridge University had died, and my heart was filled with grief.
In 2011, at the invitation of my grandfather, Professor Lu Yao of Shandong University and the College of History and Culture, Professor Di Deman was appointed as a first-class professor of Shandong University and came to Shandong University full-time to research the Boxer Movement.

Before his death, Professor Didman was a senior researcher at the Chinese Christian Religious Research Center of the King’s College London in the United Kingdom and a member of the Academic Committee of Matteo Ricci Institute of History and Culture, University of San Francisco.
He was an internationally renowned expert in modern Chinese history. He had made outstanding contributions to the Boxer Movement, the Balance Heavenly Kingdom, the history of Christianity in China and the social movement in modern China. He was a very modest and the lowkey scholar, and did not pay much attention to publishing and publishing. His most important works were published in the last ten years under the urging of research institutes and publishing houses.
他编写了两本重要著作，《基督教来华差会机构指南：16-20世纪》（Reference Guide to Christian Missionary Societies in China: From the 16th to the 20th Century，Armonk, N.Y.: M.E. Sharpe, 2009)，另外一本是《中国基督教史研究手册》（第二卷，Handbook of the History of Christianity in China, Vol. 2: 1800 to the Present，Leiden: Brill, 2009），这是两本在中国基督教史领域堪称百科全书式的著作，出版后学界受益良多。
He had written two important books, The Guide to Christian Mission Institutions in China: 16-20th Century.（Reference Guide to Christian Missionary Societies in China: From the 16th to the 20th Century，Armonk, N.Y.: M.E. Sharpe, 2009)，Another is the Handbook on the Study of the History of Christianity in China (Volume 2).Handbook of the History of Christianity in China, Vol. 2: 1800 to the Present，Leiden: Brill, 2009.These are two encyclopedic works in the field of Chinese Christian history, which have benefited a lot from their publication.
His doctoral dissertation on social conflicts in North China is also a fine work, which is often cited in western academic circles, but he had been constantly improving and revising, and had not been able to produce an English version. The Collection of Western Boxer Literature (Shandong University Press, 2016), which he had published during his work in Shandong University, was the most comprehensive book on the catalogue of Western literature of the Boxer Movement, providing a solid literature foundation and convenience for the next academic research. During his tenure at Shandong University, he had to leave mainland China briefly for Hong Kong, China, for visa reasons, and then return to Shandong University. Even so, he insisted that he devoted most of his time to the research at Shandong University every year, and had been made a lot of achievements and contributions to Shandong University.
I have known the Professor Di Deman during his work at Shandong University in 2011. At that time, I had just studied abroad. After graduating from the oversea university and returning home, I worked as a teacher in the Western Language Department of Hebei Foreign Languages College. The International Conference on History is scheduled to be held at Shandong University, which requires translators from different languages. After passing the examination, I had came to Shandong University History and the History Culture College to work. My grandfather, the Professor Lu Yao, is the academic leader of the International Modern Boxer League of Shandong University. He has invited Mr. Ditman, the professor of Cambridge University in England, to work in Shandong University then.The Professor Didman had came to Shandong University in June of the same year. My office is next to the Professor Didman. I have been had the opportunity to get along with the Professor Ditman day and night until I had left Shandong University to study abroad as a graduate student. I have been spent three years with him.
I remember the first time that I met the Professor Didman, who was German. His body is over 190cm , the blonde white hair was carefully combed. He is very handsome. He always smiled, being spoke with a sense of humour, and his manner revealed his gentleness. In his spare time, we often chat together,being accompany him to the supermarket shopping. His wife, Mrs. Anna, is Argentine and only speaks Spanish, which facilitates my contacts with the Professor and Mrs. Ditmann.
I am always consulting the Professor Ditman when I have encountered the translation problems in the collating materials. He always goes to great lengths to answer the questions and had provided me with the various materials or the references to translate sources. I felt that he knows all the relevant figures and materials in the history of Christianity in modern China, which making me admire him very much. He was the academic authority of international history. He was familiar with the materials of modern Chinese Christian history, whether Catholic or Protestant, and he had been known them well.
Every early morning, I have to clean his office before he comes to the office. He came to the office and sat there motionless until five o'clock in the afternoon. At noon, He usually has a simple food sandwich, sometimes he eat some fruit, and often share with me. Sometimes I accompany him to lunch in the student canteen. Now thinking of these as if yesterday, still vividly in mind, doing not think it has been nearly five years.
In close contact with the Professor Didman, I have learned that he had been the diagnosed with gastric cancer five years ago. Surgical treatment plus chemotherapy, miraculously, being recovered quickly.
In August 2015, the 22nd International Congress of the History and Science was held in Jinan. One of the round tables on the Boxer Movement was organized by him. More than ten experts from China, Britain, the United States, France and Germany attended. He had not only presided over the meeting, but also had wrote a long paper. The meeting was very successful. In fact, he had been attended the meeting with illness and returned to China for treatment immediately after the meeting. During this period, he had been continued to work for Shandong University and was engaged in collecting and sorting out the data of Boxer Movement.
The Professor Didman had died of the bone cancer at the age of 78. Since then, the international historiography circle has been lost an outstanding expert and scholar, and the Chinese historiography circle has been lost an admirable tutor and close friend.
