I live in Beijing. I like the dummy object here very much! : )

It isn't right. The sentence is missing an object. The verb 'like' is always a transitive verb, and it must have a noun, pronoun or a gerund as its object. 'Here' is not a noun - it's an adverb, so it can't be the object of the sentence. You can say 'I like it here very much'. The 'it' is a dummy object. It is used to complete the grammar, but it doesn't carry meaning. Alternatively, you could use a gerund as the object and say 'I like living here very much'.

Hi Helen You would say, "I live in Beijing. I like it here very much."
