I went to Yantai by boat in Dalian. I want to go to Penglai, then what island, and finally Taishan. Can you tell me the route and what bus to take? What should I pay attention to?

Please attach the name of the island. Yantai has many islands: Long Island, Kongtong Island and Mayang Island, but according to what you said, it should be Long Island. Tell me the route: after you get off the ferry, take a bus to Penglai at Yantai bus station, then take a ferry from Penglai to Long Island, and then return by train from Yantai to Taishan. This is the general route.
