What should I do if I do not have any contacts, addresses in China for Section 4.7-4.10 of the visa application?

Thank you for your advise. I now have another question: I do not yet have an itinerary for my visit to China, so I do not have any contacts, addresses, or phone numbers in China for Section 4.7-4.10 of the visa application. What should I do?
Thank you!
