The closing line of Gong Zizhen's
龚自珍 late-Qing poem 《
己亥杂诗·
其五》 (Miscellaneous Poems of 1839, no. 5):
浩荡离愁白日斜,
吟鞭东指即天涯。
落红不是无情物,
化作春泥更护花。 - 'Vast parting sorrow under the slanting sun; my whip points east toward the edge of the sky. Fallen petals are not without feeling - they turn into spring soil and shelter still more flowers.' Written when Gong resigned from office and left Beijing.
