Hotels in China: Flights to China

Chinese Visa Service

I am a US citizen and will be visiting my parents in Hong kong with my family. We plan to join a tour company for a visit to Shanghai and surrounding area. The travel agency said that they cannot provide us with proofs for individual members such as airplane tickets, hotel reservations etc since this is a group reservation. They can provide receipt that states our names, departure dates, deposits, tour number and itinerary. I can also include my roundtrip tickets receipts to HK. Is this sufficient proof?
