In Tachai Island, I acrossed the primeval forest. we saw a lot of butterflies on the huge tree branches, their size is even bigger than the magpies, I believe they are the biggest butterflies I have ever saw in my life; we found two crabs in a tree hole, their body looks like the crabs back in China but red, they say these are the only type of crabs living on land, which is very precious. When we were swimming nears the beach, some cute little sharks were swimming with us all along. ——and P.S, Tachai Island is the national forest park of Thailand, you need two hours on boat to reach there and you must walk on that island bare foot
