The University of Edinburgh, Aida for short, is one of the top 20 universities in the world, and has always enjoyed a high reputation in Britain and even the whole world. The University of Edinburgh is located in Edinburgh, the capital of Scotland. It is the world's top university founded in 1583 and the sixth oldest comprehensive research university in Britain. According to QS World University Ranking in April/May, 2065438, Edinburgh University ranks first in Scotland, sixth in Britain and seventeenth in the world [1]. On 20 14, 12 and 18, the only official REF ranking of British universities (formerly RAE) is published once every seven years, and Edinburgh University ranks fourth in the UK, second only to Oxford University, University College London and Cambridge University [2-4]. At the same time, the University of Edinburgh is also one of the most popular British universities for international students in China. The University of Edinburgh has produced 19 Nobel Prize winners [5] and three British prime ministers, and is a member of Russell Group, Universitas 2 1, coimbra group and the European Union of Research Universities. By the end of 20 14, there were more than 32,000 students studying more than 900 degree programs in Edinburgh University, among which more than 12000 international students from more than 38 countries were studying undergraduate, master's and doctoral programs respectively, and the proportion of international students has exceeded 37.5%[6]. This ratio shows that the University of Edinburgh is a truly international university and one of the few super-large universities in Britain with more than 30,000 students. Nevertheless, the University of Edinburgh has a very strict admission and selection mechanism, and the annual enrollment ratio of freshmen is only10%-1%. It is also one of the most competitive and difficult universities in Britain to apply for.
