Equipment: The ocean water in early May was extremely cold, and the wetsuit provided was a bit thin and ill-fitting, making it very chilly. Although the shop offered a thermal jacket, it was still very cold, and the wetsuit itself had a few small tears. The dive shop's showers are outdoors; while there's hot water, it's only for rinsing off, not for drinking. There's no water dispenser, and the vending machine doesn't offer hot drinks, which was particularly uncomfortable during the rainy season. Location: Due to the ocean conditions that day, we couldn't go to the Blue Cave even by boat. Since the Japanese instructor didn't speak Chinese and seemed reluctant to speak English, there was absolutely no pre-dive briefing. I didn't even know the name of the dive site. What I saw underwater was an artificial coral farm. Although there was a beautiful school of black and white tropical fish, I really wouldn't recommend this dive site; it's not as good as those in Taiwan.
