In the Caofeidian sea area in the south of Tangshan, there is an unnamed island in the shape of "L", like a fairy who deliberately throws a golden yarn between people, surrounded by the waves of Tangshan Bay. The unnamed island echoes the sisters of Caofeidian Island, which are under development and construction, with a quiet and distinctive character, and is not open to the outside world at present. Later, after the name was given to the whole society, it was shaped like a dragon, and finally named "Long Island". The island is a primitive island in the ocean, with fine sand, blue sea water, koi scales, ostriches, colorful shells everywhere, and the wilderness is full of charm. It is a precious virgin land and uncarved natural jade belt in Bohai Bay.
