Is it OK to have your outbound flight leaving from Hong Kong?

I have flight confirmation for my entry and exit from China but my outbound flight leaves from Hong Kong rather than mainland China. Could this be a problem when applying for a tourist visa? Also it states above that if you are applying for a double entry visa you should state your intention to leave (in my case to Japan) 'in the section where you list the places you will visit'. I can't see this section on the application form, just a section that asks you to list the residences that you will be staying in during your time in China. Any ideas anyone?

Thanks!
