How about Chenda Island in Taizhou?

Chenta Island is relatively backward because it is an island. Most of the daily necessities are transported into the island from Jiaojiang Wharf, but there are abundant aquatic products. The seafood you eat is a scenery that won't come up that day. Except for a few mountains, if there is nothing special to go, you can take a boat ticket at Jiaojiang Wharf, which takes about 30 hours and almost two hours. I forgot that the pier is next to Jiang Bin Park, and the accommodation is not expensive.
