If you are close, you can go and have a look. The seafood there is also good. These years have also attracted many tourists. Now Caesar has begun to develop the Daidong River, aiming to turn the Daidong River into the last virgin sea in northern China and a bright pearl over Bohai Bay. Regarding the planning, Caesar wants to build the Dadai River in Caesar into a city, which is divided into five islands. The five islands are planned according to the theme and complement each other.
