Hi
My daughter and I are Australian Citizens and will be briefly stopping in Guangzhou arriving 20.20h one day and departing 21.20h the next, on a return trip from CAMBODIA TO SYDNEY. Obviously this is just over 24 h (arrival to departure) but we would be passing through immigration (out and then in) within 24 hours. We would like to stay in a hotel overnight. Do we need visas to do this??
