Ferry is the fastest and most convenient way because it directly departs from the HK city centre. But if you have time, bus is a good option as well, it is an hour longer but $150 cheaper.
Thank you so much for all your efforts to support the beach cleaning event of Hong Kong. It is so lucky to see your guest invitation with famous Japanese actor SOKO San. He is a good Hong Kong devotee, so lot of Hongkongers love him very much. Thank you all for loving HK. Love you. You are the best, good luck, good health, enjoy your day in HK.
