On the east bank of the Bohai Sea, there is a quiet small fishing village, it is far from the hustle and bustle of the city, quiet as it was thousands of years ago, here people sunrise, sunset, hardworking and kind ancestors here fishing and swaying, live a pure and quiet life, this is double corridor. Shuanglang is the only place to pass by the Southern Silk Road. Pebbles and bluestones are inlaid in a sequence of streets and lanes. It is unclear whether the sea has been washed or washed in the years. The rows of old houses are vast, the eaves are very low, the stone feet are also very high, low-key and persistent.
