Good day. We're going to Shenzhen next month for a quick vacation with maximum stay of just 5 days or less. I was wondering what alternative documents we can present for proof of return besides hotel reservations and roundtrip tickets? We haven't actually booked any reservations yet since exact date of departure is still undecided as of the moment. We were hoping to apply for a Chinese Visa first to solve any future concerns regarding the application as early as possible before finalizing the entire trip. Looking forward to your reply. Thank You so much.
