Hi there,
Since the University course is accredited by the University of Nottingham, they should have made sure that it is of the same calibre and academic level as their courses in the UK.
If this isn't the case, then it's quite worrying. I'd be interested to know what other students are disappointed about too if you can let us know!
In terms of employability, studying abroad for your whole degree would be really good for your CV. It shows that you are motivated enough to go abroad to get a degree in what you are passionate about, are adventurous and not afraid to do different things. It can also help you to have an international career if you manage to get some work experience in China. As you said, there's nothing like learning a language in the country where it is spoken...
