reduction of relative clauses

is it possible to use any verb(,see,hear etc.)while reducing adjective clauses .if not,I; need a list of verbs not to be used.

For example?..

People (who were)fighting were taken out of the cinema by the police.
I know this is a correct reduction by using the present participle.what about these?
e.g.people liking holiday spend a lot of money on it. Here rises my question? is it possible to make such a reduction with the verbs 'like-see-hear etc.?ıf not,I need a complete list of verbs that can’t be used as above.thanks in advance

Yes, I think that those generally work grammatically.
