More than 300 RMB have been sent to sea from Langang, which has a high performance-price ratio. It includes shuttle buses, fast boats, lunch, snorkeling, swimming and boat fishing, as well as tea on the island. Start at more than 9 a.m. and come back at 2 p.m. Seawater and beach are still acceptable. There are fishermen's seafood on the island. They are sold by basin, cheap and big bowls. Fishing is an experience, the probability of catching is very small. It's a pity to snorkel. You can only see the coral but not the fish. The water is not very clear.
