Hi, I am an Indonesian Citizen. I have purchased two ways tickets Jakarta-HK and HK-Jkt. I plan to go to China for two days, from Hong Kong. When I apply for Chinese Visa, do I need to present or to bring the two ways tickets (Hk-China and China-HK), eventhough later on I will travel by train or boat (Which I plan to buy the tickets later on once I arrived in Hong Kong)?
