hi i have eu pasport and i want go china for holiday do i know visa or can get from airport there?

Ahmed, under normal circumstances, you need to apply for it from the PRC embassy in your country in advance. Only if you are eligible for the free transit policy or you are in an emergency, it's likely that you don't need the entry permit or can get it from the airport on arrival.

They will need from me booking ticket and hotel ?? If not confirm its okay ?? I will just make reservation and i will confirm after application

Ahmed, if you can get an invitation letter from some friends in PRC, then you don't need to show the hotel and tickets reservations. If you cann't obtain such letter, you need to submit the ticket and hotel booking records. I personally think the printed reservation records are ok.
