A good place to see the sea:
Rizhao Zhangjiatai Lijiatai 1: The activity here is mainly to catch the sea, which stems from its unique maritime location. At low tide, the sea can retreat as far as three kilometers from the coast, which is a good place to pick up shells, clams and crabs.
2. Renjiatai Dry Sea Garden: You can pick up fish, shrimp, shellfish and crabs on the beach. Sea sand is very good. Very soft and clean. I stayed in Rizhao for a short time, so I feel best here.
3. Taigong Island Oyster Park: This is a tidal reef. At least the whole reef will be exposed in the future. There are abundant oyster resources here. It depends on your luck.
