Duff once abused several streets in the computer department of Xiamen University. Now the gap with Xiamen University is getting bigger and bigger, and the subject evaluation is two grades worse. I brag about how strong ACM is and how fierce the competition is every day. Undergraduate students who are good at it should not be exempted from the exam by prestigious schools. Few of them should go abroad to do this kind of work. In recent years, a considerable number of graduate students from Duff University have actually been exempted or admitted to Xiamen University, and a large number of talents have been lost to Xiamen University. Although undergraduates can't compare with them, what is important for graduate students is scientific research. Xiamen University graduate students are very good at writing papers. Few graduate students can play games or concentrate on squatting in the laboratory. Although Xiamen University does not attach importance to competition, it attaches importance to scientific research. Perhaps this is also the reason why Xiamen University's computer development is better than Duff University's in recent years. Moreover, Xiamen University, with its wealth, has been introducing talents, which has led to the overall strength of Duff Computer in recent years, otherwise it would not have only got a B- in the subject evaluation. Civil architecture is also Duff's trump card, but the subject evaluation is still not very good. Not to mention the liberal arts of Duff University, such as English, have been abused by Duff Normal University for several blocks. The leaders of the School of Foreign Languages of Duff University heard that all doctors are going to study in normal universities. As Fuzhou people, they sincerely hope that Dafu can develop well and not let Fuzhou be shorter than Xiamen.
