During the summer vacation, I brought children to Beihai to play. I read the guide on the Internet and said that the Beihai Jinwan Mangrove Ecological Tourism Area was great. The consequences were worthwhile. The environment was excellent and the air was very fresh. I asked the staff to know that it was the mangrove tree that released negative oxygen ions. The air and other environmental requirements are also very high. Walking on the small wooden bridge in the mangrove forest, the eyes are green on both sides, the red tidal flat crabs 🦀️, the gray blue crabs, shuttle under the mangrove trees, the small tidal flat fish one by one, the children like it very much. The beach on the mangrove side has a lot of live shells, conch, hermit crabs, and beach crabs. The children caught a lot on the beach. It was very fun. I experienced the fun of catching the sea on the beach. It was very fun and worth recommending.
