Hi,
I take flight CZ (China Southern Airlines) to Haikou. It must take the connecting flight at Guangzhou. I would like to know if I could have some time go out of the airport to make a worship at Liu Rong Si and Guang Xiao Si? As far as I know it's just far away from the airport only 1 km.
Are there any procedures like check the health, etc before going out and in again?
How many hours does it takes from after the flight landing to the process of going out of the airport?
Also, how many hours does it take from going in the airport? 2 hours prior the flight departure?
I'm not going to spend the night there at CAN but just go to 2 places, when I leave the luggage and get back later, does it take me so long?
Sorry for many questions but I would like to go visit only 2 places in CAN during the flight stop in CAN. Thanks.
