Looking for an analysis of the image of "tears" in classical poetry.

The tears of parting, holding hands and looking at each other, the tears in the eyes are speechless and choked

The tears of the country are shattered when the flowers splash, hate the farewell, the birds are frightened

The talents are not met by the early autumn on the temples Tears flow in vain

The tears of gratitude are human and everything is not the same. No need to speak. Tears flow first

The tears of lovesickness are speechless and only a thousand lines of tears
