Hong kong-->macau--->Guilin via hong kong airport-->home

Hello

We are traveling to Hong kong macau and Guilin as tourists. We arrive in Hong kong we will then go to macau for one day before leaving for Guilin from Hong kong International airport. We will go directly from Macau to the airport by ferry. After Guilin we will fly home from Hong kong. We are Swedish citizens. Do we need 1 or 2entries to China and do we need a Hong kong visa??

Best regards
Emilie
