If I am in Enping City, Guangdong Province, I will take Air Canada AC032 HKG/YYZ

No direct ferry is available. But I have to two suggestions for this trip:
1. Take a bus from Enping General Bus Station to Jiangmen. Then take a taxi to Jiangmen Port to catch a ferry to China Ferry Terminal in HK. Only one ferry is in service each day, leaving at 15:00. Near China Ferry Terminal, you can take free shuttle bus line Kk2 to Kowloon Station. There you can check in and directly take Airport Eexpress to HKIA.
PS. As the ferry doesn't directly head for HKIA, the lugagge check-in service may be unacceptable.
2. At Enping General Bus Station, take a direct bus to Guangzhou and get off at the Provincial Bus Station. Then take a taxi to Garden Hotel. Nearby you can catch a direct bus to HKIA and it takes around 4h to arrive.
