I planned to go to Macau from Hong kong but I'm not sure how to take train, bus or ferry?

Well, I have just found the ferry operating between two cities on the internet. You can take the ferry at HK (Sheung Wan) Port to Macau Outer Port. The ferry operates from 07:00 to 23:59 with the interval of 15 minutes. It will also depart at 00:30, 01:00, 01:30, 02:30, 04:15 and 06:00 at night. The duration is about 55 minutes. The ticket of economy class cost HK$164/person for a day sailing in weekdays and HK$177/person on weekends and holidays. The economy class of night sailing may charge HK$200/person.

Thank you so much for information.
