Author: Li Bai
Old friends frequently waved to me, bid farewell to the Yellow Crane Tower, and traveled to Yangzhou in this beautiful spring filled with catkins and flowers.
My friend's sail shadow faded away and disappeared at the end of the blue sky, only seeing the first line of the Yangtze River and heading for the distant horizon.
The meaning of this sentence in the poem is that in the spring of March, I went to Yangzhou for a long trip, and the catkins were everywhere, and the birds were singing and the flowers were fragrant.
The meaning of combination in the whole poem:
Old friends frequently waved to me, bid farewell to the Yellow Crane Tower, and traveled to Yangzhou on this catkin-like, flowery March spring day.
The lonely sail shadow of my friend faded away and disappeared at the end of the blue sky, only seeing a line of the Yangtze River, heading for the distant sky.
The profound friendship between Li Bai and Meng Haoran, as well as the treasure and attention to friendship, are all shown here.
