How the **** is china a dictatorship?

I hate it when stupid and ignorant little kids talk about a country/countries they have never lived in. I mean sure, there is a lack of free press, and tibet is treated really shitly, but how is that different from how England treated Northern Ireland? All websites talk about how the chinese communist party, but where do their sources come from? i've lived in china for 1 and a half years and I know what im talking about. Everyone has the right to find a better job, get a good education and have a family.
