Is there a 3 13 seaside in Xingcheng or Huludao? I remember the waves were high. Is there clean water now?

Huludao Longwan seaside is 3 13 seaside, and the train station takes busNo. 1. The waves are high when it is windy, and the sea is dirty when there is no wind. That time, I walked a long way and saw a river ditch discharging sewage from the inland into the sea. It was dirty and smelly, but there were still people swimming in the sea. Xingcheng seaside is cleaner than 3 13. If you want to swim, go to Xingcheng seaside.
