Back to the poem in the Ming Dynasty when the prince

The poem in 'Return to the Ming Dynasty as a Prince' was: I bury you in the mud and bones under the spring, I send you to the world, my head full of snow. This sentence came from the Tang Dynasty poet Bai Juyi's "Farewell to the Ancient Grass." It means that even if I am buried in the spring, I will entrust my grief to the place where no one goes.
