The poem "Suddenly someone said, looking back at the mountains and rivers is spring" expresses the nostalgia for the past friendship and the feeling of the passage of time. This poem is from Ji Hai Miscellaneous Poems written by Gong Zizhen in Qing Dynasty. The original sentence is "suddenly there is a friend's heart, and it is autumn to look back on the mountains and rivers."
Later, someone changed this poem and turned it into "suddenly someone has loved, and it is spring to look back on the mountains and rivers." This change not only retains the emotional charm of the original poem, but also makes the artistic conception of the poem broader and more touching.
