I went to Rock Island in January 2019. First of all, there were not many Chinese, but many Europeans. Secondly, the island's eco-environment is just as beautiful as the small island in which it was photographed, such as Pirates of the Caribbean & gt. I don't know what words to describe it. It's just breathtaking. I don't see any sign forbidding littering on the island, but who else has the heart to leave litter on such a beautiful island? The water is clear, the beach is white, the sand is as fine as flour, plus beautiful coral reefs. If there is a real heaven, I think it's just like that. Don't talk too much nonsense, go straight to the picture!
