Cheung Po Tsai Cave
Time Out says
This marks the spot where one of the most notorious Chinese pirates, Cheung Po-tsai, who once commanded a fleet of 600 ships and was the inspiration behind Chow Yun-fat’s character Sao Feng in Pirates of the Caribbean, used to hide his booty. While there’s no cursed gold or fabulous treasures left, alas, it’s fun to travel through the dark and narrow underground passages. Just remember to bring a torch and maybe a parrot.
