半城樱花半城雨
[bàn chéng yīng huā bàn chéng yŭ]
Cherry blossoms represent romance, beauty and impermanence while rain can symbolize sadness and melancholy in China’s poetic traditions. The user might mean that one half of his/her heart is filled with beautiful romanticism (as cherry blossom), and the other with nostalgia (as rainfall).
