In this blatant and blundering age, the masters are scarce. After the death of some masters such as Zhang Dainian, Ji Xianlin, Tsien Hsueshen and so on, there is almost no master left. They used to be the great teachers of Tsinghua University and their scientific attainments, moral quality and patriotic feeling have affected millions upon millions of students and lasted for a long time. Opening the massive record of Tsinghua, we are exclamatory that it shares weal and woe with the calamitous Chinese people. From the 1901 Indemnity and establishment of Tsinghua School to warlords division of the country and the rising revolution tides, war of resistance against Japanese and establishment of National Southwest Association University by the vagrant teachers and students to the KMT-CPC civil war and the establishment of the new China, political activities of anti-rightist, socialist education of four clear-ups and cultural revolution to the reform and opening up, Tinghua University has gone through a hundred years of changes, sacrifices and wars, reflecting the whole Chinese People and witnessing all the sufferings and efforts of China.
