hi
we will arrive at macau then go to hong kong immediately by ferry for 2 days tour.
later proceed to shenzhen for 2 days and then stay 1 night at zhuhai.
at zhuhai we plan to go to macau for 1/2 day tour and back to zhuhai for the same night
then next morning go to macau again for the return flight.
do we need to apply for double-entry visa or multiple visa?
