Going to the sea means that people living by the sea go to the mangrove sponge beach to dig snails and other things according to the law of the tide. Going to the sea is usually done during high tides. When the sea water recedes, these shellfish and seafood are left on the beach or mudflat. In the Mangrove Happy Going to the Sea Attraction, you can enjoy the wonders of the mangroves, get in close contact with the mangroves, and experience the novelty of digging sand crabs, bamboo snails, and sandworms.
