Hello, I want to apply for 2 entry visa valid 6 months (entering china on 7th april,

but applying now in Poland before leaving country). As I decided to go traveling around the world I left my job - is it ok to write unemployed on the application form? Or this might cause rejection? What shoudl I write than? I left my job on 30.11 so will be fine If i state I still work in the company? Can they check it?
Also is it ok I apply 4 months before - I do want to do it in my home country befire I leave for the trip

Thanks for help!
