What two allusions did the author use to express his feelings in the first of the three songs "It's Hard to Go to Heaven"?

I sat on a fishing rod and lay lazily by the stream. It is said that I fished on the north bank of Weihe River and met him. But I suddenly dreamed that I was driving a boat and sailing towards the sun. It is said that Yi Yin dreamed that he was crossing the edge of the sun and the moon by boat before he met the soup.

His strong demand to actively join the WTO finally freed him from the anguish of indecision and regained his confidence and lofty sentiments. "One day, I will ride the long wind, break through the huge waves, raise my muddy sails and build a bridge on the deep sea!" I firmly believe that although there are many obstacles ahead, one day, as Zong Yi said in Liu Song, I will ride the wind and waves, hang up the Yun Fan, cross the sea and reach the ideal shore.
