自在飞花轻似梦无边丝雨细如愁
[zì zài fēi huā qīng sì mèng wú biān sī yŭ xì rú chóu]
'Flowing petals as free as dreams, endless drizzles fine as sorrow' describes a poetic, melancholic mood or scenery. These words are adapted from classical Chinese poetry which convey emotions and moods with deep sentiment and romantic beauty.
