There is no difference between Cai Dong's two books and a new diploma. They are divided into two colleges, the International Business School of Surrey International College. If you study at Surrey International College (the tuition fee is 25,000 yuan in the first two years and 45,000 yuan in the second two years), you can also get a double degree from Cai Dong and Surrey University in the UK (the UK ranks between 20 and 30, and tourism management is one of the best in the UK). However, it should be noted that if you study in an international business school (that is, the one that earns 25,000 yuan in four years and only enrolls students in Liaoning Province), you can't get a double degree, which is a disadvantage compared with Surrey International College. However, the accountant offered by BCCHK is the same as the diploma of Cai Dong Accounting Institute. Everyone knows that accounting is Cai Dong's trump card, so you need to think carefully about choosing a university. Another difference is that if you attend two universities, four years of university will not be too easy, because there are many classes (after all, you have paid so much tuition), so you must work hard.
Generally speaking, it is like this. There is no difference between one book and two books after graduation. Personally, I think the advantages of the two books seem more obvious.
