Which is better, Dalu Island or Ruyi Island? Seek raiders! thank you

I'm from Shenyang, and I just got back from Zhang Dao! If you simply take a bath, catch the sea and eat seafood, Ruyi Island is still very cheap! Swimming rings are in 5 yuan every day, and each bed in the farmhouse 15 yuan. We stayed for two nights, ate three meals of seafood, and picked a dozen catties of clams! He also visited North Korea's border defense barracks and other scenic spots by speedboat in Dandong. A family of three only spent less than 1500 yuan.
