Cardiff doesn't recommend going. As for why, there are some British prejudices.
Strathclyde doesn't recommend it. It used to be a third-rate university, but recently it suddenly became popular. Many intermediaries in Britain recommend it. Don't go. I saw this university when I went to Glasgow, and you will regret it. You can't go to college at all! Compared with Glasgow University, it is very irritating.
Loughborough is average, the city is not big, and there are many people in China. But the school ranking is not bad.
Oxford Brookes, actually, this is ok. In Oxford, near London, you can accumulate work experience if you have a job opportunity.
As for the major, in fact, the major you applied for is still relatively new in Britain. As long as you study hard, you will be fine. If you have nothing to do, run to the library and have a good class. Britain is as simple as that. Actually, it's not that hard.
As a girl studying in the UK, I will give you some advice ~
