The tide is flat and the shore is wide, and the wind is sailing. Where did it come from?

The tide is flat and the shore is wide, and the wind is sailing. Use Tang Wangwan's "The next berth on Beibao Mountain" "Until the bank at low tide widens, there is no wind to stir my lonely sail". It means that the beaches on both sides of the river are wide and there are no sails to hang on. It means that in the face of the excellent situation of smooth sailing, we should strive to realize our ideals or achieve great things.
