The new leaves in Fanglin urge the old leaves to come from Liu Yuxi's seven-character poem "Three Gentlemen Divide Poems Deeply for Their Merits", which means that everything is thriving, and the new leaves on the tree urge the old leaves to change.
The phrase "the new leaves of Fanglin urge the old leaves, and the waves before flowing water make the waves after" generally means that the new leaves of trees urge the old leaves in spring, and the waves before flowing river make the waves after moving forward. This poem, translated into a well-known sentence, is that the waves behind the Yangtze River push the waves before, and a new generation replaces the old.
The significance of ancient poetry
This poem for Bai Juyi was written in memory of Yuan Zhen and other old friends. In addition to expressing deep sorrow and gratitude, it also comforted the friends who are still alive. All three gentlemen have a deep point, because it is a poem. Lamenting the passage of two quatrains and playing short songs makes me sad. There are few empty surprises and old friends in the world, and there are many concentrated sacrifices. The new leaves in Fanglin urge the old leaves, and the waves before the water are the waves after. I've always hated it. How about crying at the piano?
